摘要:

The initial boundary value problem for a viscoelastic equation

|ut|ρ uttuutt +∫t 0g(t-su(s)ds+|mut| ut = |u|p u

in a bounded domain is considered, where ρ,m,p > 0 and g is a nonnegative and decaying
function. The general uniform decay of solution energy is discussed under some conditions
on the relaxation function g and the initial data by adopting the method of [14, 15, 19].
This work generalizes and improves earlier results in the literature.
