Elliptic Operators

  • Lester L. Helms
Part of the Universitext book series (UTX)


Up to this point, all of the concepts pertain to the Dirichlet and Neumann problems for the Laplacian. In this and later chapters, the Laplacian will be replaced by an elliptic operator as described below and mixed boundary conditions will be allowed that specify the value of a function on part of the boundary and the value of its normal derivative on the remainder of the boundary as in Theorem 8.5.7.
