%0 Journal Article %T Density estimates for phase transitions with a trace %A Yannick Sire %A Enrico Valdinoci %J Mathematics %D 2010 %I arXiv %X We consider a functional obtained by adding a trace term to the Allen-Cahn phase segregation model and we prove some density estimates for the level sets of the interfaces. We treat in a unified way also the cases of possible degeneracy and singularity of the ellipticity of the model and the quasiminimal case. %U http://arxiv.org/abs/1011.6617v1
