Abstract
In this paper, we study the existence of nontrivial to the following Hamiltonian strongly degenerate elliptic system in whole space
where
are nonnegative functions with
and V might unbounded or vanish at infinity. Here
is the strongly degenerate operator and the nonlinearity terms
are continuous functions and satisfy some assumptions that will be specified later. Due to the unbounded or vanishing of potentials and degeneracy of the operator, some new compact embedding theorems are used in the proof. Our results extend and generalize some existing results.
