报告摘要：In order to prove our result on the regularity of stable solutions up to the boundary we will be forced to work with nonlinearities f that are only locally Lipschitz (and not necessarily C^{1}). Hence, it is important for us to extend the definition of stability to this class of nonlinearities. For this, we need to choose a precise representative for f’. We introduce the relevant definitions and some technical lemmata. A universal bound on the L^{1} norm is also given for proving the main results.
