Asymmetric heteroclinic double layers

Let W be a non-negative function of class C 3 from 2 to , which vanishes exactly at two points 𝐚 and 𝐛. Let S 1 (𝐚,𝐛) be the set of functions of a real variable which tend to 𝐚 at - and to 𝐛 at + and whose one dimensional energy

E 1 (v)= W(v)+| v ' | 2 / 2dx
is finite. Assume that there exist two isolated minimizers z + and z - of the energy E 1 over S 1 (𝐚,𝐛). Under a mild coercivity condition on the potential W and a generic spectral condition on the linearization of the one-dimensional Euler-Lagrange operator at z + and z - , it is possible to prove that there exists a function u from 2 to itself which satisfies the equation
-Δu+DW(u) 𝖳 =0,
and the boundary conditions
lim x 2 + u(x 1 ,x 2 )=z + (x 1 -m + ),𝐚lim x 2 - u(x 1 ,x 2 )=z - (x 1 -m - ),lim x 1 - u(x 1 ,x 2 )=𝐚,z + (x 1 -m + )lim x 1 + u(x 1 ,x 2 )=𝐛.
The above convergences are exponentially fast; the numbers m + and m - are unknowns of the problem.
