This paper establishes the emergence of slowly moving transition layer solutions for the
 $p$
-Laplacian (nonlinear) evolution equation,
 $u_t = \varepsilon^p(|u_x|^{p-2}u_x)_x - F'(u), \qquad x \in (a,b), \; t > 0,$
where
 $\varepsilon>0$
and
 $p>1$
are constants, driven by the action of a family of double-well potentials of the form
 $F(u) = \frac{1}{2\theta}|1-u^2|^\theta,$
indexed by
 $\theta>1$
,
 $\theta\in \mathbb{R}$
with minima at two pure phases
 $u = \pm1$
. The equation is endowed with initial conditions and boundary conditions of Neumann type. It is shown that interface layers, or solutions which initially are equal to
 $\pm 1$
except at a finite number of thin transitions of width
 $\varepsilon$
, persist for an exponentially long time in the critical case with
 $\theta = p$
, and for an algebraically long time in the supercritical (or degenerate) case with
 $\theta>p$
. For that purpose, energy bounds for a renormalized effective energy potential of Ginzburg–Landau type are established. In contrast, in the subcritical case with
 $\theta , the transition layer solutions are stationary. Citation: Raffaele Folino, Ramón G. Plaza, Marta Strani.
