Singular Adams inequality for biharmonic operator on Heisenberg Group and its applications

The goal of this paper is to establish singular Adams type inequality for biharmonic operator on Heisenberg group. As an application, we establish the existence of a solution to ΔHn2u=f(ξ,u)ρ(ξ)ainΩ,u|∂Ω=0=∂u∂ν|∂Ω,where 0 ∈ Ω ⊆ H⁴ is a bounded domain, 0≤a≤Q,(Q=10). The special feature of this problem is that it contains an exponential nonlinearity and singular potential.
