A strict maximum principle for nonlocal minimal surfaces

Suppose that two nonlocal minimal surfaces are included one into the other and touch at a point. Then, they must coincide. But this is perhaps less obvious than what it seems at first glance. This se...

Logarithmic Intersection Theory

Abstract: Let C be a Riemann surface, x_1,...,x_n a set of points on C, and a_1,...,a_n integers adding up to 0. The theorem of Abel and Jacobi determines when C carries a meromorphic function wi...

Computational geometry algorithms applied to an efficient semi-Lagrangian scheme for Fokker-Planck equations on unstructured grids

Semi-Lagrangian schemes are characteristic-based methods for the numerical solution of hyperbolic partial differential equations (PDEs), which maintain stability under large Courant numbers.However, t...

Complete cohomogeneity one solitons for G_2 Laplacian flow

Bryant’s Laplacian flow is an analogue of Ricci flow that seeks to flow an arbitrary initial closed G_2-structure on a 7-manifold toward a torsion-free one, to obtain a Ricci-flat metric with holonomy...

A numerical scheme for the critical value approximation of eikonal Hamilton–Jacobi equations on networks

A numerical algorithm for the Mañé critical value approximation of eikonal Hamilton–Jacobi equations on networks is presented. The proposed method is based on the long time approximation of the corres...

On moduli spaces of Fano varieties and their singularities

Fano varieties are projective varieties with “positive curvature”. Examples of Fano varieties are projective spaces, products of projective spaces, Grassmannians and hypersurfaces in projective spaces...

Learn2Solve: A Deep Learning Framework for Real-Time Solutions of forward, inverse, and UQ Problems

Digital models (DMs) are designed to be replicas of systems and processes. At the core of a digital model (DM) is a physical/mathematical model that captures the behavior of the real system across tem...

Non-commutative Iwasawa theory of abelian varieties

Non-commutative Iwasawa theory has emerged as a powerful framework for understanding deep arithmetic properties over number fields contained in a p-adic Lie extension and their precise relationship to...

Runge-Kutta Discontinuous Galerkin Methods Beyond the Method of Lines

In the common practice of the method-of-lines (MOL) approach for discretizing a time-dependent partial differential equation (PDE), one first applies spatial discretization to convert the PDE into an ...

A Mountain Pass Theorem and moduli space of minimal immersions

We present a new Mountain Pass Theorem for a class of functionals that depends on two arguments which only partially satisfies the Palais-Smale condition. This abstract functional setup will be a...

A NOTION OF S-FRACTIONAL MASS FOR 1-CURRENTS IN HIGHER CODIMENSION

We will introduce and discuss a notion of s-fractional mass for 1-currents, generalizing the s-fractional perimeter in the plane to higher codimension singularities. We will present basic compactn...
