Abstract:

The existence of solutions to Dirichlet problems for a class of singular superlinear $k$-Hessian systems with parameters is studied. Based on the Krasonsel'skii type fixed point theorem in a Banach space, the existence, multiplicity and nonexistence results of nontrivial radial solutions are obtained. At the same time, the asymptotic behavior dependent on parameter is discussed.

Key words: Radial solution, Dirichlet problem, Coupled $k$-Hessian equations, Krasonsel'skii type fixed point theorem
