Abstract
In this article, we study the well-posedness theory for solutions of the stochastic heat equations with logarithmic nonlinearity perturbed by multiplicative Levy noise. By using Aldous tightness criteria and Jakubowski version of the Skorokhod theorem on non-metric spaces along with the standard L2 method, we establish the existence of a path-wise unique strong solution. Moreover, by using a weak convergence method, we establish a large deviation principle for the strong solution of the underlying problem. Due to the lack of linear growth and locally Lipschitzness of the nonlinear term present in the underlying problem, the logarithmic Sobolev inequality and the nonlinear versions of Gronwall inequalities play a crucial role.
