Nonexistence of result for some p-Laplacian Systems

We study the nonexistence of positive solutions for the system where ? denotes the p-Laplacian operator defined by p ? ? ? ? ? ????? p ,)( xvfu ????? ????? x, 0 ,)( vu xugv p ? ? ???? p p ? 2 1?p and ??is a smooth bounded domain in R N )1( ?N , with smooth boundary )|(| zzdivz ,?? and ? are positive parameters.
