Abstract
This paper is concerned with a parabolic-parabolic Keller- Segel-type system in a bounded domain ℧ ℝ N (with N = 2 or N = 3) presenting source and damping terms. We impose Neumann and Robin boundary conditions to each one of the two unknowns of the problem and study the non-negative solutions which blow up in finite time t∗. In this way, it is possible to derive explicit lower bounds for t∗ under appropriate conditions on the data of the problem.File | Size | Format | |
