摘要

We study the viscoelastic pseudo-parabolic Kirchhoff equation with logarithmic nonlinearity \(\begin{aligned} u_t-M(\left\| \nabla u\right\| ^2)\Delta u -\alpha \Delta u_t+\int _{0}^{t}h(t-s)\Delta u(s){\textrm{d}}s=\vert u\vert ^{p-2}u\ln \vert u\vert \end{aligned}\) u t - M ( u 2 ) Δ u - α Δ u t + 0 t h ( t - s ) Δ u ( s ) d s = | u | p - 2 u ln | u | and examine the effects of the viscoelastic term and the logarithmic nonlinearity on the asymptotic behavior of its weak solutions.
