Resumen: The aim of this talk is to introduce the topic of asymptotic expansions and approximation schemes for p-Laplacian type operators. We will present the results in collaboration with J. J. Manfredi and M. Parviainen ([3]). Here, we show a unified framework to prove convergence of approximation schemes for boundary value problems regarding normalized p-Laplacian, which has to be treated in the context of viscosity solutions. While for the normalized p-Laplacian, asymptotic expansion and finite difference discretizations were very well known, this was not the case for p-Laplapcian. In the second part of the talk, we will present such results. This is a work in collaboration with E. Lindgren ([1, 2]). Here, we introduce new asymptotic expansions and finite difference discretizations and show convergence of approximation schemes for associated problems.
