报告摘要:In this talk, we first discuss a diffusion model of Kirchhoff-type driven by fractional Laplace operator. Under some appropriate conditions, the local existence of nonnegative solutions is obtained by employing the Galerkin method. Then, by means of a differential inequality technique, we prove that the local nonnegative solutions blow up in finite time with arbitrary negative initial energy and suitable initial values. Moreover, we give an estimate for the lower and upper bounds of the blow-up time. The main feature of our problems is that the Kirchhoff function could be zero at zero. Finally, we present some recent results for some degenerate Kirchhoff-type evolution problems involving the fractional Laplacian.
