The Allen-Cahn equation is a simple example for reactiondiffusion
equations with bistable nonlinearity. For this
equation, the existence and stability of two-dimensional
V-form fronts are proved by Ninomiya and T(2005). $N$-
dimensional cylindrically symmetric traveling fronts are
studied by Hamel, Monneau and Roquejoffre(2005, 2006)
and Chen, Guo, Ninomiya, Hamel, Roquejoffre(2007).
Traveling fronts of pyramidal shapes are studied by T
(2007) and Kurokawa-T(2011). In this talk I will explain
my recent work and show that there exists an $N$-
dimensional traveling front associated with an $(N-1)$-
dimensional strictly convex compact set.
