摘要

This paper is concerned with a general fully parabolic Keller- Segel system, defined in a convex bounded and smooth domain Ω of R~N, for N∈{2,3}, with coefficients depending on the chemical concentration, per- turbed by a logistic source and endowed with homogeneous Neumann bound- ary conditions. For each space dimension, once a suitable energy function in terms of the solution is defined, we impose proper assumptions on the data and an exponential decay of such energies is established.
