초록

In this paper, we proved the exponential growth of solutions for a quasilinear viscoelastic wave equation with logarithmic nonlinearity. Under suitable conditions $u_0 \in V$, $u_1 \in L^{2}(\Omega) \cap L^{\rho+1}(\Omega)$, and initial energy (i) $0 < E(0) < \frac{k}{4}\gamma < d$ and (ii) $E(0) <0$, we establish the asymptotic behavior for a class of energy.
