Au+ Ke 2u= l on S 2(1.1) where A denotes the Laplacian relative to the standard metric. The question raised by L. Nirenberg is: which function K can be prescribed so that (1.1) has a solution? There is an obvious necessary condition implied by integration of (1.1) over the whole sphere:(with dkt denoting the standard surface measure on S 2) fs Ke2Udl~= 4er.(1.2)(t) Research supported in part by NSF; grants and the Forschungsinstitut fiir Mathematik, ETH Ziirich, Switzerland.
