Local minimizers in d of vector Allen-Cahn with a quadruple junction
Abhishek Adimurthi, Peter Sternberg
For a perturbation of the unit ball in , we establish the existence of a sequence of local minimizers for the vector Allen-Cahn energy. The sequence converges in…

Minimizing solutions of degenerate Allen-Cahn equations with three wells in
Lia Bronsard, Ãtienne Sandier, Peter Sternberg
We characterize all minimizers of the vector-valued Allen-Cahn equation in under the assumption that the potential has three wells and that the associated degene…
