In this paper we are concerned with positive solutions of the doubly nonlinear parabolic equation ut=div(um-1|∇u| p-2∇u)+Vum+p-2 in a cylinder Ω×(0,T), with initial condition u(·,0)=u0(·) ≥ 0 and vanishing on the parabolic boundary ∂Ω×(0,T). Here Ω⊂RN (resp. Hn) is a bounded domain with smooth boundary, VLloc1(Ω), mR, 1
