報(bào)告摘要:In this talk, we introduce the blow-up phenomenon of the three-dimensional nonlinear Kirchhoff equation with focusing power nonlinearities. The global non-existence for a kind of nonlinear Kirchhoff equations has been shown by Autuori, Pucci and Salvatori. We prove that this equation admits a blow-up solution which approaches the ODE blow-up profile in a backward light cone by overcoming the difficulty causing from the Kirchhoff operator.
