Abstract: In this paper, we first study the cone Moser–Trudinger inequalities and their best exponents on both bounded and unbounded domains R+2. Then, using the cone Moser–Trudinger inequalities, we study the asymptotic behavior of Cerami sequences and the existence of weak solutions to the nonlinear equation −ΔBu=f(x,u),in x∈int(B),u=0,on ∂B, where ΔB is an elliptic operator with conical degeneration on the boundary x1=0, and the nonlinear term f has the subcritical exponential growth or the critical exponential growth.

Keywords: Cone Moser–Trudinger inequalities, best exponent, asymptotic estimate, rearrangement, mountain pass theorem
