摘要: Following classical work by Freidlin [Trans. Amer. Math. Soc. (1988) 305 665--657] and subsequent works Sowers [Ann. Probab. (1992) 20 504--537] Peszat [Probab. Theory Related Fields (1994) 98 113--136], we prove large deviation estimates for the small noise limit of systems stochastic reaction--diffusion equations with globally Lipschitz but unbounded diffusion coefficients, however, assuming reaction terms to be only locally polynomial growth. This generalizes results above mentioned authors. Our apply, in particular, Ginzburg--Landau multiplicative noise.
