1. Allen Cahn Equation Energy: Phase transition model. Let › µ RN of a \binary mixture": Two materials coexisting (or one material in two phases). We can take as an example of this: Water in solid phase (+1), and water in liquid phase (¡1). The conflguration of this mixture in › can be described as a function u⁄(x) = ‰ +1 in ⁄ ¡1 ...
