This paper deals with properties of the solution of a parabolic system of two quasilinear equations of the form \[ u_ t=\Delta u^{\nu +1}+v^ p,\quad v_ t=\Delta v^{\mu +1}+u^ q, \] where \(\mu\),\(\nu\),p,q are positive numbers. Let \(m=pq-(1+\mu)(1+\nu)\), then the case \(m\leq 0\) determines conditions for the global solvability of the boundary value problem and the other case gives a criterion for the location of the unbounded solutions of the Cauchy problem.
