Reaction-Diffusion Equations

Abstract

We shall consider here a stochastic heat equation pertubed by a polynomial term off odd degree d > 1 having negative leading coefficient (this will ensure non-explosion). We can represent this polynomial as $\begin{array}{*{20}{c}} {\lambda \xi - p(\xi ),} & {\xi \in \mathbb{R},} \\ \end{array}$ where λ ∈ ℝ and p is an increasing polynomial, that is p′(ξ) ≥ 0 for all ξ ∈ ℝ.
