“…Furthermore, the author showed a polynomial decay estimate in the L 2 ‐norm for the solutions of this problem. Finally, we refer the reader to [
36, 37] where the author has discussed the global existence, asymptotic behavior, and blow‐up of solutions for classes of parabolic equations involving the
‐Laplacian with logarithmic nonlinearity. Notice that, if
and
, then the equation in (1.1) reduces the following one:
In this paper, we shall show that solving a wave equation involving the nonlinear fractional p ‐Laplacian via the Galerkin method is much easier than solving the usual quasilinear wave equations like those in ( P ).…”
