## Invited Speakers

◎ KIAS Plenary Lecture (4.29(토) 16:20~17:10)

 최희준   Choe, Hi Jun     • 연세대학교 응용해석 및 계산 센터장       Director, Center for Mathematical Analysis & Computation   at Yonsei University • 연세대학교 수학과 교수       Professor, Department of Mathematics, Yonsei University        Title: Leading to Mathematical Fluid Mechanics The motion of fluid is complex and fascinating. Meanwhile our understanding of the behavior is very much limited in both phenomena and rigorous mathematics. In material sense, fluid is something like water, air and oil that change their shapes according to container. Because all materials are made of particles like atoms, the motion of fluid is modeled from Hamiltonian dynamics, statistical mechanics and continuum mechanics. In this talk we address foundation, mechanical equations and mathematical challenges. Although most mathematical issues are old and intensely studied, many of them stand firmly open. We like to discuss about mathematical progresses and trend.

 [대수학 Algebra]  박진형   Park, Jin Hyung       • 고등과학원 수학부 연구원   Researcher, School of Mathematics, Korea Institute for Advanced Study   (KIAS)• 2016년도 상산젊은수학자상 수상자    The winner of 2016 Sangsan Prize for Young Mathematicians      Title: Potentially non-klt locus and its applicationsThe potentially non-klt locus of a log pair was introduced to measure singularities and the positivity of anticanonical divisor. This locus is birationally transformed precisely into the non-klt locus on a anticanonical minimal model. In this talk, I explain basic properties of potentially non-klt locus in comparison with those of classical non-klt locus, and then, give some applications including a characterization of varieties of Fano type and the rational connectedness of uniruled varieties. This is joint work with Sung Rak Choi.

 [해석학 Analysis]  이한주   Lee, Han Ju         • 동국대학교 수학교육과 교수   Professor, Department of Mathematics Education, Dongguk University     Title: Geometry of Banach spaces and norm-attaining operatorsThe celebrated Bishop-Phelps theorem says that the set of norm-attaining bounded linear functionals is norm-dense in the dual space of a Banach space. As Lindenstrauss showed, this does not holds, in general, for bouned linear operators between Banach spaces instead of linear functionals. There has been a lot of effort to characterize the denseness of bounded linear opeartors from a Banach space X to Y. As Lindenstrauss and Bourgain showed, these are closed related to the geometric properties of Banach spaces such as uniform convexity, smoothness and Radon-Nikodym property. Recently, a new quantitative property is actively studied in this topic. This is called a Bishop-Phelps-Bollobas property for operators. I briefly review some geometric notion of Banach spaces and present recent related results about the Bishop-Phelps-Bollobas property for operators.

 [기하학 Geometry]  최재경   Choe, Jaigyoung         • 고등과학원 수학부 교수   Professor, School of Mathematics, Korea Institute for Advanced Study   (KIAS)       Title: Ricci curvature and Riemannian manifoldsI will present a dichotomy on manifolds of nonnegative Ricci curvature.

 [위상수학 Topology]  김현규   Kim, Hyun Kyu    • 이화여자대학교 수학과 교수   Professor, Department of Mathematics, Ewha Womans University• 2016년도 대한수학회상 상산젊은수학자상 수상자    The winner of 2016 Sangsan Prize for Young Mathematicians    Title: Quantum Teichm\"{u}ller theoryThe Teichm\"{u}ller space of a surface with boundary is the set of all isotopy classes of complex structures on the surface. It is equipped with a Poisson or symplectic structure, preserved under the natural action of the mapping class group of the surface. Quantum Teichm\"{u}ller theory establishes an equivariant deformation quantization of the Teichm\"{u}ller space, regarding the above structures. Namely, it replaces smooth functions on the Teichm\"{u}ller space by self-adjoint operators on a Hilbert space which carries the information on the Poisson structure, and to each mapping class group element assigns a unitary operator intertwining the self-adjoint operators. In this talk I give an introduction to this subject, and discuss some consequences, including mapping class group representations, 3-manifold invariants, 2d conformal field theory, and 3d quantum gravity.

 [응용수학 Applied Mathematics]  천세훈   Chun, Se Hun         • 연세대학교 융합과학공학부 교수   Professor, Department of Integrated Science and Engineering Division,    Yonsei University      Title: Method of moving frames for scientific computingScientific computing enjoyed unprecedented success since its emerging in 1950s. In modern times, it however faces many stumbling stones in computational simulations for the regeneration and prediction of natural phenomena. One of them is geometry in Riemannian sense. The world is full of curved objects made of anisotropic materials that are even moving at different speed and direction. Even state-of-the-art computational techniques are inaccurate and/or unstable, or at least very expensive for geometrically-realistic modeling. The only way to overcome this difficulty seems to hammer realistic objects and their trajectory into the projection of Euclidean framework. However, another breakthrough was achieved through a peculiar perspective of Elie Cartan who saw the world 100 years ago as a collection of infinitesimally Euclidean, isotropic, and possibly static objects. In this talk, I will talk about how Cartan’s unique geometric theory in the continuous world, called method of moving frames, has been adapted to the discrete world of computer to provide us an efficient tool and perspective to represent the geometry of the world, especially for meteorology, electrodynamics, and cardiology.

 [이산수학 Discrete Mathematics]  서승현   Seo, Seung Hyun            • 강원대학교 수학교육과 교수   Professor, Department of Mathematics Education, Kangwon National University     Title: Integer partitions with prescribed successive rank parity blocksSuccessive ranks of a partition, which were introduced by Atkin, are the difference of the $i$th row and the $i$th column in the Ferrers diagram. Recently, in the study of singular overpartitions, Andrews revisited successive ranks and parity blocks. Motivated by his work, we investigate partitions with prescribed successive rank parity blocks. The main part of this talk is the generating function of partitions with exactly $d$ successive ranks and $m$ parity blocks. With this generating functions, we also present $q$-series identities including a truncated version of Euler's pentagonal number theorem.This talk is based on the joint work with Ae Ja Yee.

 [수학교육 Mathematical Education]  Robert A. Beezer    • Professor, Mathematics and Computer Science, University of Puget Sound       Title: Open software and open Textbooks for mathematics In this talk, I will describe and demonstrate some recent technological advances for teaching and communicating mathematics.Sage is open source software for advanced mathematics.

 [확률 및 통계학 Probability and Statistics]  김정심   Kim, Jeong Sim              • 충북대학교 수학교육과 교수      Professor, Department of Mathematics Education, Chungbuk National University        Title: Performance analysis of polling systems with processor-sharing disciplineWe consider a polling system with a single server and multiple queues where customers arrive at the queues according to independent Poisson processes. The server visits and serves the queues in a cyclic order. The service discipline at all queues is exhaustive service. One queue uses processor-sharing as a scheduling policy, and the customers in that queue have phase-type distributed service requirements. The other queues use any work-conserving policy, and the customers in those queues have generally distributed service requirements. We derive a partial differential equation for the transform of the conditional sojourn time distribution of an arbitrary customer who arrives at the queue with processor-sharing policy, conditioned on the service requirement. We also derive an equation for the transform of the unconditional sojourn time distribution. From these equations, we obtain the first and second moments of the conditional and unconditional sojourn time distributions.This is a joint work with Bara Kim (Korea University).
