KW - Global existence, blowup, logarithmic and polynomial combined nonlinearity, potential well.
AB - <p style="text-align: justify;">The semilinear wave equation with logarithmic and polynomial nonlinearities is considered in this paper. By adjusting and using potential well
method, we attain the global-in-time existence and infinite time blowup solutions at subcritical initial energy level $E(0)&lt;d.$&nbsp;Then using additional conditions
on initial data, these results are enlarged at critical case $E(0)=d$ and arbitrarily
positive case $E(0)&gt;0.$</p>
