Positive solutions of singular elliptic problems with unbounded exponents and unbounded convection term
In this paper, we study the existence of a solution for a class of Dirichlet problems with a singularity and a convection term. Precisely, we consider the existence of a positive solution to the Dirichlet problem $$-Δ_p u = \fracλ{u^α} + f(x,u,\nabla u)$$ in a bounded, smooth domain $Ω$. The convection term has exponents with no upper limitations neither in $u$ nor in $\nabla u$. This is somewhat unexpected and rare. So, we address a wide range of problems not yet contained in the literature. The solution of the problem combines the definition of an auxiliary problem, the method of sub- and super-solution and Schauder's fixed point theorem.
