摘要

In this paper we propose some inequalities in an attempt to explore the structure of a class of fully nonlinear equations. As an application, we solve some Krylov-type equations on closed Riemannian manifolds of quasi-admissibility. Notably, without topological obstruction, we may construct some metrics with prescribed curvature functions. The method and inequalities developed here should be useful to deal with other fully nonlinear equations of elliptic and parabolic type.
