摘  要：In this talk, I’ll discuss some recent results obtained in joint works with Peter Polacik (Minnesotta) and with Hiroshi Matana (Tokyo) on the long-time behavior of the solution to the nonlinear parabolic problem

\[u_t-\Delta u=f(u)\; (x\in R^N, t>0), u(x,0)=u_0(x)\; (x\in R^N),\]

where $u_0\in L^\infty(R^N)$ is nonnegative and has compact support, $f$ is a smooth function satisfying $f(0) = 0$.
