A necessary and sufficient condition for the existence of large solutions for (p1,…,pd)(p1,…,pd)-Laplacian Schrödinger systems with a convection term

Recent work on the existence of a large solution for different elliptic systems, including the sublinear elliptic system and the mixed type elliptic system, has focused on some nonlinear problems. In this paper, a necessary and sufficient condition for the existence of positive entire radial solutions in nonlinear Schrödinger problems with (p1,…,pd)(p1,…,pd)-Laplacian is investigated by successive approximation.
