摘要:  We raised a conjecture that for an embedded hypersurface in a Euclidean space, the explicit formula of Green function for GJMS operator coincides with that of GJMS operator with respect to the round metric, then the hypersurface is a round sphere.

We give a positive answer to the above conjecture for the conformal Laplacian, and the Paneitz operator in almost all cases. This is based on joint work with Yalong Shi, and a project in progress with Jiaxue Gan and Yalong Shi.
