초록

This paper deals with the blow-up phenomenon of solutions to a pseudo-parabolic equation with logarithmic nonlinearity, which was studied extensively in recent years. The previous result depends on the mountain-pass level $d$ (see \eqref{d} for its definition). In this paper, we obtain two blow-up conditions which do not depend on $d$. Moreover, the upper bound of the blow-up time is obtained.
