A singular elliptic equation with natural growth in the gradient and a variable exponent
In this paper we consider singular quasilinear elliptic equations with quadratic gradient and a singular term with a variable exponent (Formula presented.) Here Ω is an open bounded set of RR, γ(x) is a positive continuous function and f is positive function that belongs to a certain Lebesgue space....
