Ponente: Félix del Teso (Universidad Complutense de Madrid)Fecha: miércoles 27 de octubre de 2021 - 15:00Lugar: Online - us06web.zoom.us/j/81491079139?pwd=OWo1TWc0NEExNDJZUFljWVRIdkZRQT09 (ID: 814 9107 9139; Access code: 937701)
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 (). 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.
