Life span of solutions with large initial data for a class of coupled parabolic systems. (English) Zbl 1270.35138
Summary: This paper deals with a class of coupled systems of parabolic equations subject to large initial data. By constructing and solving a new ODE system, we obtain the accurate life span of solutions (blow-up time) of the expression determined by the initial value.
