张土生教授报告(一)
题目: A probabilistic approach to mixed boundary value problems  of elliptic PDEs with singular coefficients
报告人:张土生(英国曼切斯特大学教授)
报告时间:2018年8月6日上午 8:00---11:00 报告地点:数学楼145报告厅
摘要:The purpose of our work is to use probabilistic methods to solve the mixed boundary value problem for  linear and semilinear second order elliptic partial differential equations with singular coefficients.
Our approach is probabilistic. The theory of Dirichlet forms and backward stochastic differential equations will play an important role.

题目:Global solutions to stochastic reaction-diffusion equations with super-linear drift and multiplicative noise
报告人:张土生(英国曼切斯特大学教授)
报告时间:2018年8月6日下午 2:30---5:30 报告地点:数学楼145报告厅
摘要: Consider stochastic reaction-diffusion equations driven by multiplicative space-time white noise. When the noise disappears, , it is well known that such PDEs with superlinear frequently have non-trivial stationary solutions. By contrast, Bonder and Groisman  have recently shown that there is finite-time blowup when there is appearance of noise. In this paper, we prove that the Bonder--Groisman condition is unimproveable. We present two essentially-different ways of approaches without altering the conclusions of our assertions.
