Blow-up and global existence for the heat equation with nonlinear absorption-diffusion

扫码查看
This paper deals with blow-up of positive solution of the nonlinear heat equation with absorption subject to a nonlinear boundary condition. The conditions under which the solutions may exist globally or blow-up are obtained by the comparison principles.
