We consider degenerate fully nonlinear equations, whose degeneracy rate depends on the gradient of solutions. First, we impose a Dini-continuity condition on the degeneracy term and prove that solutions are continuously differentiable. Then we focus on a work-horse of the theory, namely equations degenerating as a power of the gradient, and prescribe a free transmission problem. In this context, we discuss the existence of solutions and their optimal regularity. We conclude the talk by commenting on a currently open problem in the theory.
