Existence of positive solutions to a singular boundary-value problem using variational methods

open access: yesElectronic Journal of Differential Equations, 2014
In this article, we study a class of nonlinear singular boundary-value problems. We show the existence of positive weak solutions by using variational methods.

Mountain-Pass Solutions in 2D Turbulence with Generalized Sobolev Operators [PDF]

open access: yes
This work extends the study of mean field equations arising in two-dimensional (2D) turbulence by introducing generalized weighted Sobolev operators. Employing variational methods, particularly the mountain pass theorem and a refined blow-up analysis, we
