안녕하세요, 

기초교육학부에서 2024년도 지스트 과학문화주간을 맞이하여 <수학 간담회>와 <수학 강연시리즈 1,2>를 준비하였습니다.

아래와 같이 개최하오니, 관심 있는 구성원께서는 참석하여 주시기 바랍니다.

Title Principles and recent developments in statistical mechanics

Speaker 노승한 박사 (하버드 물리학과)

Abstract

In the Newtonian framework, the future trajectory of a physical system can be determined from its initial conditions using the equations of motion. However, the power of this formalism is limited to one- or two-body systems. For three or more bodies, the dynamics become chaotic, making precise predictions impossible. So, how do physicists calculate the properties of many-body systems, such as chemical mixtures or electronic devices? In this seminar, I will introduce the formalism of statistical mechanics, which tames chaotic behavior through combinatorial state number counting. I will also briefly explore recent developments that have deepened our understanding of nonequilibrium systems.

Title Wave turbulence and some well-posedness results

Speaker 라준현 교수 (고등과학원 수학부)

Abstract

Wave turbulence refers to the statistical theory of weakly nonlinear dispersive waves. In the weakly turbulent regime of a system of dispersive waves, its statistics can be described via a coarse-grained dynamics, governed by the kinetic wave equation. Remarkably, kinetic wave equations admit exact power-law solutions, called Kolmogorov-Zakharov spectra, which resemble Kolmogorov spectrum of hydrodynamic turbulence, and is often interpreted as a transient equilibrium between excitation and dissipation. In this talk, we will outline a local well-posedness result for kinetic wave equation for a toy model for wave turbulence. The result includes well-posedness near K-Z spectra, and demonstrates a surprising smoothing effect of the kinetic wave equation. The talk is based on the joint work with Pierre Germain (ICL) and Katherine Zhiyuan Zhang (Northeastern).

참석인원이 많을 경우 강연장이 변동될 수 있으며, 변동사항은 참석신청을 해주신 분들께 별도 안내드릴 예정입니다.

감사합니다.
