Abstract:
In this paper one considers nonlinear parabolic boundary-value problems of a general form. It is known that the solution of such problems can go to infinity in a finite interval of time. One shows that this effect is in a certain sense of a finite-dimensional character. Namely, one shows that if the solution is considered on the segment [0,T], while the right-hand sides are bounded in the norm by a constant R and satisfy a finite number of conditions, then the problem admits a solution which is smooth for 0⩽t⩽T (the number of conditions depends on R and T).
