On the triple junction problem with general surface tension coefficients

Nicholas D. Alikakos, Zhiyuan Geng

We investigate the Allen-Cahn system \begin{equation*} Δu-W_u(u)=0,\quad u:\mathbb{R}^2\rightarrow\mathbb{R}^2, \end{equation*} where is a pote…

Identifying the Relationship between Seasonal Variation in Residential Load and Socioeconomic Characteristics

Zhenyu Wang, Hao Wang

Smart meter data analysis can provide insights into residential electricity consumption behaviors. Seasonal variation in consumption is not well understood but yet important to uti…

Entire minimizers of Allen-Cahn systems with sub-quadratic potentials

Nicholas D. Alikakos, Dimitrios Gazoulis, Arghir Zarnescu

We study entire minimizers of the Allen-Cahn systems. The specific feature of our systems are potentials having a finite number of global minima, with sub-quadratic behaviour local…

On Almost Entire Solutions Of The Burgers Equation

Nicholas Alikakos, Dimitrios Gazoulis

Solutions that satisfy classically the Burgers equation except, perhaps, on a closed set S of the plane of potential singularities whose Hausdorff 1-measure is zero, ,…

Stability Criteria for Multiphase Partitioning Problems with Volume Constraints

N. D. Alikakos, A. C. Faliagas

We study the stability of partitions involving two or more phases in convex domains under the assumption of at most two-phase contact, thus excluding in particular triple junctions…

Density estimates for vector minimizers and applications

Nicholas D. Alikakos, Giorgio Fusco

We extend the Caffarelli-Cordoba estimates to the vector case in two ways, one of which has no scalar counterpart, and we give a few applications for minimal solutions.

Asymptotic behavior and rigidity results for symmetric solutions of the elliptic system

Nicholas D. Alikakos, Giorgio Fusco

We study symmetric vector minimizers of the Allen-Cahn energy and establish various results concerning their structure and their asymptotic behavior.

A maximum principle for systems with variational structure and an application to standing waves

Nicholas D. Alikakos, Giorgio Fusco

We establish via variational methods the existence of a standing wave together with an estimate on the convergence to its asymptotic states for a bistable system of partial differe…

On the structure of phase transition maps for three or more coexisting phases

Nicholas D. Alikakos

This paper is partly based on a lecture delivered by the author at the ERC workshop "Geometric Partial Differential Equations" held in Pisa in September 2012. What is presented her…

Plateau angle conditions for the vector-valued Allen-Cahn equation

Nicholas D. Alikakos, Panagiotis Antonopoulos, Apostolos Damialis

Under proper hypotheses, we rigorously derive the Plateau angle conditions at triple junctions of diffused interfaces in three dimensions, starting from the vector-valued Allen-Cah…

A new proof for the existence of an equivariant entire solution connecting the minima of the potential for the system Δu - W_u (u) = 0

Nicholas D. Alikakos

Recently, Giorgio Fusco and the author studied the system Δu - W_u (u) = 0 for a class of potentials that possess several global minima and are invariant under a general finite ref…

A replacement lemma for obtaining pointwise estimates in phase transition models

Nicholas D. Alikakos, Giorgio Fusco

We establish a replacement lemma for a variational problem, which is not based on a local argument. We then apply it to a phase transition problem and obtain pointwise estimates.

Some basic facts on the system Δu - W_u (u) = 0

Nicholas D. Alikakos

We rewrite the system Δu - W_u (u) = 0, for u: R^n to R^n, in the form div T = 0, where T is an appropriate stress-energy tensor, and derive certain a priori consequences on the so…

Entire solutions to equivariant elliptic systems with variational structure

Nicholas D. Alikakos, Giorgio Fusco

In the present paper we consider the system Δu - W_u (u) = 0, where u: R^n to R^n, for a class of potentials W: R^n to R that possess several global minima and are invariant under…

On an elliptic system with symmetric potential possessing two global minima

Nicholas D. Alikakos, Giorgio Fusco

We consider the system Δu - W_u (u) = 0, for u: R^2 -> R^2, W: R^2 -> R, where W_u (u) is a smooth potential, symmetric with respect to the u_1, u_2 axes, possessing two global min…

Heteroclinic Travelling Waves of Gradient Diffusion Systems

N. I. Katzourakis, N. D. Alikakos

We establish existence of travelling waves to the gradient system connecting two minima of when $u : \R \times (0,\infty) \larrow \R^N$, that is, w…
