Let W be a non-negative function of class C3 from 2 to , which vanishes exactly at two points a and b. Let S1(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 / 2 x is finite. Assume that there exist two isolated minimizers z+ and z- of the energy E1 over S1(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 - Δ u + W ( u ) 𝖳 = 0 , and the boundary conditions lim x 2 + u ( x 1 , x 2 ) = z + ( x 1 - m + ) , 𝐚 lim 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.
