Robin problems with measure data and singular nonlinearities on the boundary

We consider the Robin problem for a uniformly elliptic divergence operator with measure data on the right-hand side of the equation and an absorption term on the boundary involving blowing up terms. We prove the existence of a positive renormalized solution and provide its stochastic representation, which can be viewed as a generalized nonlinear Feynman–Kac formula. From this representation we derive some additional regularity results for the solution and some uniqueness results.
