Goals are (1) to estimate the conditional response distribution addressing the distributional changes across the predictor space, and (2) to identify important predictors for the response distribution change both within local regions and globally. We rst introduce the probit stick-breaking process (PSBP) as a prior for an uncountable collection of predictor-dependent random distributions and propose a PSBP mixture (PSBPM) of normal regressions for mod-eling the conditional distributions. A global variable selection structure is incorporated to discard unimportant predictors, while allowing estimation of posterior inclusion probabili-ties. An ecient stochastic search sampling algorithm is proposed for posterior computation. The methods are illustrated through simulation and applied to an epidemiologic study.   ASARC Seminar Examples of (non) Stein domains and manifolds. Dan Jaffran (KAIST) 2010-03-09   I will give an introduction to Stein complex manifolds. I will describe basic examples and non examples for domains in complex Euclidean space. Trickier examples arise from the interplay with isolated singularities of surfaces, an interesting topic in its own. I will assume familiarity with smooth manifolds, and interest in the field of several complex variables.   BK21 Seminar Asymptotic Behavior of Invariant Metrics Lina Lee (University of Michigan) 2010-03-09   I will give a brief introduction to invariant metrics (the Kobayashi, Carath'eodory, Bergman, and Sibony metric) and explain how the asymptotic behavior of the metrics near the boundary of a domain is related to the geometry of the boundary. The talk will be accessible to graduate students.   KAIST 수리과학과 콜로퀴움(2010년 1학기) Introduction to Toric Topology Suh Dongyoup (KAIST) 2010-03-04     KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 7 Takahiko Yoshida (Meiji University) 2010-03-02       KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 6 Takahiko Yoshida (Meiji University) 2010-02-26      KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 5 Takahiko Yoshida (Meiji University) 2010-02-26      KAIST Toric Topology Workshop 2010 On the first homology of automorphism groups of G-manifolds 2 Kojun Abe (Shinshu University) 2010-02-26      KAIST Toric Topology Workshop 2010 On the first homology of automorphism groups of G-manifolds 1 Kojun Abe (Shinshu University) 2010-02-26      KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 4 Takahiko Yoshida (Meiji University) 2010-02-26      KAIST 수리과학과 콜로퀴움(2010년 1학기) Apollonian Circle Packings Oh Hee (Brown University) 2010-02-25     KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 3 Takahiko Yoshida (Meiji University) 2010-02-25      KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 2 Takahiko Yoshida (Meiji University) 2010-02-25      KAIST Toric Topology Workshop 2010 On construction of locally standard Z2-torus actions on manifolds Li Yu (Nanjing University) 2010-02-25      KAIST Toric Topology Workshop 2010 Schubert calculus, seen from torus equivariant topology 2 Shizuo Kaji (Fukuoka University) 2010-02-25      KAIST Toric Topology Workshop 2010 Schubert calculus, seen from torus equivariant topology 1 Shizuo Kaji (Fukuoka University) 2010-02-25      BK21 Seminar EigenValue Problem III Shu Feng Xu (Peking University) 2010-02-24      KAIST Toric Topology Workshop 2010 Moment-angle manifolds in toric topology 4 Taras Panov (Moscow State University) 2010-02-24      KAIST Toric Topology Workshop 2010 Moment-angle manifolds in toric topology 3 Taras Panov (Moscow State University) 2010-02-24      BK21 Seminar EigenValue Problem II Shu Feng Xu (Peking University) 2010-02-23      KAIST Toric Topology Workshop 2010 RR=#BS via localization of index 1 Takahiko Yoshida (Meiji University) 2010-02-23      KAIST Toric Topology Workshop 2010 Combinatorial rigidity of 3-dimensional simplicial polytopes Suyoung Choi (Osaka City University) 2010-02-23      KAIST Toric Topology Workshop 2010 Introduction to lagrangian floer theory in toric manifolds 1 Cho, Cheol Hyun (Seoul National University) 2010-02-23      KAIST Toric Topology Workshop 2010 A convexity theorem for three tangled Hamiltonian torus actions Hiraku Abe (Tokyo Metropolitan University) 2010-02-23      KAIST Toric Topology Workshop 2010 Introduction to lagrangian floer theory in toric manifolds 2 Cho, Cheol Hyun (Seoul National University) 2010-02-23      BK21 Seminar EigenValue Problem I Shu Feng Xu (Peking University) 2010-02-22      KAIST Toric Topology Workshop 2010 Symmetry of a symplectic toric manifold Mikiya Masuda (Osaka City University) 2010-02-22      KAIST Toric Topology Workshop 2010 Coisotropic submanifolds of symplectic manifolds, leafwise fixed points, and presymplectic embeddings Fabian Ziltener (University of Toronto) 2010-02-22      KAIST Toric Topology Workshop 2010 The cohomology ring of the GKM graph of a flag manifold Yukiko Fukukawa (Osaka City University) 2010-02-22      KAIST Toric Topology Workshop 2010 Symplectic real bott manifolds Hiroaki Ishida (Osaka City University) 2010-02-22      KAIST Toric Topology Workshop 2010 Moment-angle manifolds in toric topology 2 Taras Panov (Moscow State University) 2010-02-22      KAIST Toric Topology Workshop 2010 Moment-angle manifolds in toric topology 1 Taras Panov (Moscow State University) 2010-02-22      KAIST Discrete Math Seminar The 3-Color Problem Tommy R. Jensen (Kyungpook National University) 2010-02-19   The fundamental sufficient condition for the existence of a proper 3-coloring of the vertices of a planar graph G was proved by Grötzsch more than 50 years ago, and it requires that G has no triangles (cycles of length 3). This talk discusses conjectures for other possible sufficient conditions, some of which have stubbornly resisted proofs for decades, and also various recent partial results. A conjecture in a different direction deals with a stronger 3-colorability property, which for a planar graph turns out to be equivalent to triangle-freeness, but here it is unknown whether the assumption of planarity may be weakened.   KAIST Discrete Math Seminar The Fibonacci dimension of a graph Sergio Cabello (University of Ljubljana) 2010-02-10   The Fibonacci dimension fdim(G) of a graph G is introduced as the smallest integer f such that G admits an isometric embedding into the f-dimensional Fibonacci cube. We will see combinatorial relations between the Fibonacci dimension and the isometric or lattice dimension, and establish the Fibonacci dimension for certain families of graphs. Finally, we will discuss the problem of computing the Fibonacci dimension, namely, its NP-hardness and approximation algorithms.   ASARC Seminar 매듭과 소수 III Masanori Morishita (Kyushu University) 2010-02-10     ASARC Seminar 매듭과 소수 II Masanori Morishita (Kyushu University) 2010-02-09     ASARC Seminar 매듭과 소수 I Masanori Morishita (Kyushu University) 2010-02-09     KAIST 수리과학과 콜로퀴움(2010년 1학기) Knots and Primes - Hyperbolic Geometry and Galois Deformation Masanori Morishita (Kyushu University) 2010-02-08     KAIST Seminar Mathematics of Bose Gas Lee Jioon (Harvard University) 2010-02-08   The properties of the Bose gas has been studied by many authors, and since the first experimental observation of Bose-Einstein Condensation, interests in low temperature Bose gas are renewed. In this talk, a mathematical framework to understand Bose gas will be introduced. Heuristics and rigorous proofs for the ground state energy of Bose gas will also be explained.   2010 ASARC WORKSHOP Fermat's last theorem and deformation theory of Galois representations Choi, Suhhyun (KAIST) 2010-02-06   I will introduce the idea of the proof of Fermat's last theorem of Wiles and Taylor, and try to explain how the deformation theory is used in the proof.   2010 ASARC WORKSHOP Homological Mirror Symmetry conjecture. Cho Cheolhyun (Seoul National University) 2010-02-06   We explain  ideas and conjectures of homological mirror symmetry and its basic ingredients (but not its proof).   2010 ASARC WORKSHOP Homotopy algebras and non-commutative geometry. Cho Cheolhyun (Seoul National University) 2010-02-06   We explain how homotopy algebras, such as A-infinity algebras arise in mathematica physics and explain the its relation to geometric concepts in non-commutative algebras.   2010 ASARC WORKSHOP Special families of linear subspaces and their applications in algebraic geometry Fyodor L.Zak (Independent University) 2010-02-05     2010 ASARC WORKSHOP Hilbert functions of almost reverse lexicographic ideals Park, Jungpil (NIMS) 2010-02-05   We introduce Moreno-Socias conjecture on generic initial ideals of ideals generated by generic forms, which is closely related with Fr"{o}berg conjecture. Then we study Hilbert functions of almost reverse lexicographic ideals. We give an equivalent condition for a given sequence of nonnegative integers to be the Hilbert function of an almost reverse lexicographic ideal.   2010 ASARC WORKSHOP Partial dg-categories and mixed over k[t]/(t^{m+1}) Park Jinhyun (KAIST) 2010-02-05   In this informal, and supposed to be a friendly talk, we generalize the formalism of Bondal and Kapranov that associates a (pre)-triangulated category to each dg-category to what we call "partial" dg-categories. A partial dg-category is almost a dg-category where compositions of morphisms are defined only on a class of quasi-isomorphic subcomplexes of the given dg-complexes, that we call "distinguished subcomplexes". This idea originates from M. Hanamura, in his construction of the triangulated category of mixed motives over a perfect base field k. We axiomatize this method, and extend Hanamura's category of motives to a category of motives over the truncated polynomial rings k[t]/(t^{m+1}). The essential new ingredient is a moving lemma for additive higher Chow groups that the speaker proved recently. Since this is supposed to be a colloquium style talk, I will give a sketch of definitions of various objects, and in particular no proofs will be given. The audience is expected to listen to the flow and the story only. I will try to be as elementary as possible, and I hope the audience can learn at least something from the talk.   2010 Korean TEX Society Annual Meeting and Conference Beamer와 TikZ의 활용 Cho Myungchul (Korea University) 2010-01-30     2010 Korean TEX Society Annual Meeting and Conference TnXTeX and xoblivoir Kim Gangsoo (KTUG) 2010-01-30     2010 Korean TEX Society Annual Meeting and Conference Fontspec package Lee Juho (NABO) 2010-01-30     2010 Korean TEX Society Annual Meeting and Conference XeTeX-ko Kim Dohyun (Dongguk University) 2010-01-30     2010 Korean TEX Society Annual Meeting and Conference Introduction to XeTeX Cho Jinhwan (Suwon University) 2010-01-30
