Abstract: We study the problem of existence of positive, spherically symmetric strong solutions of quasilinear elliptic equations involving p‐Laplacian in the ball. We allow simultaneous strong dependence of the right‐hand side on both the unknown function and its gradient. The elliptic problem is studied by relating it to the corresponding singular ordinary integro‐differential equation. Solvability range is obtained in the form of simple inequalities involving the coefficients describing the problem. We also study a posteriori regularity of solutions. An existence result is formulated for elliptic equations on arbitrary bounded domains in dependence of outer radius of domain.
