Prescribed scalar curvature problem
From Wikipedia, the free encyclopedia
In Riemannian geometry, a branch of mathematics, the prescribed scalar curvature problem is as follows: given a closed, smooth manifold M and a smooth, real-valued function ƒ on M, construct a Riemannian metric on M whose scalar curvature equals ƒ. Due primarily to the work of Jerry Kazdan and Frank Wilson Warner in the 1970s, this problem is well understood.
