| contents | In this paper, we consider the initial boundary value problem of a doubly nonlinear parabolic equation with nonlinear perturbation. We impose the homogeneous Dirichlet condition on this problem. We aim to reduce the growth condition of the nonlinear term and the largeness of exponent as possible so that we can apply our result to both singular and degenerate type parabolic equations. We use in our proof the $L ^{\infty }$-estimate of the time-discrete equation derived in the previous work and apply the so-called $L ^{\infty }$-energy method to the time-discrete problem. We also discuss the uniqueness of solution by using the previous result. |
