Density estimates for a degenerate/singular
phase-transition model
(54K, LaTeX)

ABSTRACT.    We consider a Ginzburg-Landau type phase-transition model driven by
  a $p$-Laplacian type equation.  We prove density estimates for
  absolute minimizers and we deduce the uniform convergence of level
  sets and the existence of plane-like minimizers in periodic media.
