p-q Laplace system is closely related to fluid mechanics, arises in the study of non-Newtonian fluids or in the theory of quasiregular and quasiconformal mappings. With extremely extensive application background and deep research value, the existence and nonexistence of solutions of p-q Laplace systems have received more and more attention recently by domestic and foreign scholars.
This paper mainly from the view of Partial Differential Equations is specifically divided into three parts to study the exi...
