| dc.description.abstract | The purpose of this paper is to prove the existence of solutions for certain types of nonlinear parabolic partial differential equations posed in the whole space, when the data are assumed to be merely locally integrable functions, without any control of their behaviour at infinity. A simple representative example of such an equation is ut - Δu + |u|s-1 u = ƒ, which admits a unique globally defined weak solution u(x, t) if the initial function u(x, 0) is a locally integrable function of x ∈ ℝN and t ∈ [0, T] whenever the exponent s is larger than 1. The results extend to parabolic equations. They have no equivalent for linear or sub-linear zero-order nonlinearities. | |
