Regularity and finite element approximation for two-dimensional elliptic equations with line Dirac sources
Hengguang Li, Xiang Wan, Peimeng Yin +1
We study the elliptic equation with a line Dirac delta function as the source term subject to the Dirichlet boundary condition in a two-dimensional domain. Such a line Dirac measur…
