Eigenvalue Inequalities for Fully Nonlinear Elliptic Equations via the Alexandroff-Bakelman-Pucci Method

Dimitrios Gazoulis

In this work we establish eigenvalue inequalities for elliptic differential operators either for Dirichlet or for Robin eigenvalue problems, by using the technique introduced by Al…

Gradient Bounds and Liouville theorems for Quasi-linear equations on compact Manifolds with nonnegative Ricci curvature

Dimitrios Gazoulis, George Zacharopoulos

In this work we establish a gradient bound and Liouville-type theorems for solutions to Quasi-linear elliptic equations on compact Riemannian Manifolds with nonnegative Ricci curva…

On the Stability and Convergence of Physics Informed Neural Networks

Dimitrios Gazoulis, Ioannis Gkanis, Charalambos G. Makridakis

Physics Informed Neural Networks is a numerical method which uses neural networks to approximate solutions of partial differential equations. It has received a lot of attention and…

Applications of P-functions to Fully Nonlinear Elliptic equations: Gradient Estimates and Rigidity Results

Dimitrios Gazoulis

We introduce the notion of functions for fully nonlinear equations and establish a general criterion for obtaining such quantities for this class of equations. Some applicati…

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…
