Here f L2 (), Rn bounded.
The weak formulation of the equation is as follows:

And the uniformly ellipticity holds. That is:

Lecture notes on Green function on a Remannian Manifold
Nov. 26th
Let (M , g ) be a compact Riemannian manifold possibly with boundary. M M with M, M oriented.
We dene the following dieretial operator on the Riemannian manifold:
L = g + aI
Here a L (M ) a

Basics of Dierentiable Manifolds
A dierentiable manifold M is a topological space which is locally homeomorphic to an open subset of
Rn and whose transition functions are smooth maps between these open subsets. Using the
