Exponential decay of the solutions for nonlinear multiharmonic equations Original Research Article

The purpose of this paper is to establish the exponential decay properties of the solutions for the nonlinear multiharmonic equation View the MathML source{(−Δ)Ku+a(x)u=g(x,u),u∈HK(RN)⋂C2K(RN), Turn MathJax on where the condition u∈HK(RN)u∈HK(RN) plays the role of a boundary value condition.
