Blowup for the Heat Equation with a Noise Term
In this paper we study blowup of the equation u t = u xx + u _ W tx , where _ W tx is a two-dimensional white noise eld and where Dirichlet boundary conditions are enforced. It is known that if < 3=2, then the solution exists for all time; in this paper we show that if is much larger than 3=2, then the solution blows up in nite time with positive probability. We prove this by considering how pe...
متن کاملSharp Global Existence for Semilinear Wave Equation with Small Data
The global existence in time for nonlinear wave equation with small data usually require high Sobolev regularity, when one dealt with them by classical energy method (see [Kl85] [Ch85]). The purpose of this note is to give the sharp regularity global existence for semilinear equation with the power nonlinearity of the derivative, the counterpart of quasilinear equation or the quadratic nonlinea...
