Convergence rate of the finite element approximation for extremizers of Sobolev inequalities
Woocheol Choi, Younghun Hong, Jinmyoung Seok
In this paper, we are concerned with the convergence rate of a FEM based numerical scheme approximating extremal functions of the Sobolev inequality. We prove that when the domain…
