Title：Life Span for a Semilinear Heat Equation with Initial Data non-Rarefied at \infty
Speaker：Jingxue Yin (South China Normal University)
Time：16:00-17:00, August9
Location：Room 201，Ming De Building
Abstract：In this talk, we discuss the life span of solutions for the heat equation with nonlinear sources. We will show that as long as the initial datum is non-rarefied at $\infinity$, the solution must blow up at finite time. Moreover, we give an delicate estimate on the life span.
