报告题目: Solutions and continuum limits to nonlocal discrete sine-Gordon equations: bilinearization reduction method
报告人:赵松林
报告简介:In this talk, we investigate local and nonlocal reductions of a discrete negative order Ablowitz-Kaup-Newell-Segur equation. By the bilinearization reduction method, we construct exact solutions in double Casoratian form to the reduced nonlocal discrete sine-Gordon equations. Then, nonlocal semi-discrete sine-Gordon equations and their solutions are obtained through the continuum limits. The dynamics of soliton solutions are analyzed and illustrated by asymptotic analysis. The research ideas and methods in this talk can be generalized to other nonlocal discrete integrable systems.
