Global existence and exponential decay of solutions for higher-order parabolic equation with logarithmic nonlinearity
Tugrul Cömert; Erhan Piskin;Abstract
This paper deal with the initial boundary value problem for a higher-order parabolic equation with logarithmic source term
u_{t}+(-\Delta )^{m}u=u^{r-2}u\ln\left\vert u\right\vert.
We show that the global existence of weak solution, by employing the potential wells technique. Also, we obtain the exponential decay for the weak solutions.
