ABSTRACT

This paper investigates the problem of non-existence of global solutions for a general spatial–temporal fractional evolution equation: ρ(x)cD0/tαu+(Δ)β/2uΔum+auq=h(x,t)|u|p,(x,t)RN×(0,+).Using the test function method, necessary and sufficient conditions are established. The results are extended to a class of an incommensurate fractional spatial–temporal system.
