地点：报告人：邱春晖教授工作单位：厦门大学报告时间：19日下午2:30报告地点：学院南研究生教室报告摘要：In this paper, we first give several comparison theorems and their applications in Finsler geometry. Moreover, by means of the Hessian comparison theorems of a real Finsler manifold, Cartan connection, radial flag curvature and tangent curvature, we give Wu’s theorem on a strongly convex weakly K¨ahle...

地点：报告人: 吴付科  教授工作单位: 华中科技大学报告时间:10月19日下午4:30报告地点: 数学与统计学院一楼报告厅 报告摘要:  In contrast to the use of white noise in stochastic models, wideband noise is more realistic for various applications. White noise is a good process to work with, but it is difficult to realize in real applications, whereas wideband noise is a good approximation to white noise. This ...

地点：报告人:吕琦教授工作单位: 四川大学报告时间：10月20日上午9点报告地点：数学与统计学院一楼报告厅报告摘要:  We present some recent progresses on the linear quadratic control problems for stochastic evolution equations. The main novelty is that the diffusion term contains a control and the operator R is not assumed to be positive. We study the closed-loop solvability of this problem. This solvability...
