Γ-convergence of higher-order phase transition models
We investigate the asymptotic behavior as ɛ→0 of singularly perturbed phase transition models of order n≥2, given by Gɛλ,n[u]≔∫I1ɛW(u)−λɛ2n−3(u(n−1))2+ɛ2n−1(u(n))2dx,u∈Wn,2(I),where λ>0 is fixed, I⊂R is an open bounded interval, and W∈C0(R) is a suitable double-well potential. We find that there...

| Riassunto: | We investigate the asymptotic behavior as ɛ→0 of singularly perturbed phase transition models of order n≥2, given by Gɛλ,n[u]≔∫I1ɛW(u)−λɛ2n−3(u(n−1))2+ɛ2n−1(u(n))2dx,u∈Wn,2(I),where λ>0 is fixed, I⊂R is an open bounded interval, and W∈C0(R) is a suitable double-well potential. We find that there exists a positive critical parameter depending on W and n, such that the Γ-limit of Gɛλ,n with respect to the L1-topology is given by a sharp interface functional in the subcritical regime. The cornerstone for the corresponding compactness property is a novel nonlinear interpolation inequality involving higher-order derivatives, which is based on Gagliardo-Nirenberg type inequalities. |
