Abstract
In this paper we formulate new curvature functions on via integral operators. For certain even orders, these curvature functions are equivalent to the classic curvature functions defined via differential operators, but not for all even orders. Existence result for antipodally symmetric prescribed curvature functions on is obtained. As a corollary, the existence of a conformal metric for an antipodally symmetric prescribed curvature functions on is proved. Curvature function on general compact manifold as well as the conformal covariance property for the corresponding integral operator are also addressed, and a general Yamabe type problem is proposed.
