Finite element approximation of an obstacle problem for a class of integrodifferential operators Academic Article uri icon

abstract

  • We study the regularity of the solution to an obstacle problem for a class of integrodifferential operators. The differential part is a second order elliptic operator, whereas the nonlocal part is given by the integral fractional Laplacian. The obtained smoothness is then used to design and analyze a finite element scheme.
