摘要: In this paper, we derive the a priori estimates for a class of more general $(k,l)$-Hessian quotient type equations involving $u$ and $Du$ on the right hand function. As an application we prove the Liouville theorem depending on Pogorelov type estimates. On the other hand, we obtain the existence and uniqueness of the $k$-admissible solution for these general equations with the Neumann boundary condition, based on some growth conditions for the right hand function.
