Critical points for a functional involving critical growth of Trudinger-Moser type (Q2512914)

From the abstract: We establish the existence of critical points of least energy functionals associated with a class of singular quasilinear equations involving critical growth of Trudinger-Moser type. For this, in line with Concentration-Compactness Principle due to \textit{P. L. Lions} [Rev. Mat. Iberoam. 1, No. 1, 145--201 (1985; Zbl 0704.49005)], we study the lack of compactness of Sobolev imbedding in Orlicz space defined in \(\mathbb{R}^n\).
