Non-uniqueness for the Complex Ginzburg-Landau Equation

Joel Dahne, Vladimír Šverák

We show that singularities of the three-dimensional cubic complex Ginzburg-Landau equation developing from smooth initial data can induce non-uniqueness of solutions after the time…

Monotonicity of the first Dirichlet eigenvalue of regular polygons

Joel Dahne, Javier Gómez-Serrano, Joana Pech-Alberich

In this paper we prove that the first Dirichlet eigenvalue of an -sided regular polygon of fixed area is a monotonically decreasing function of for all , a…

Self-Similar Singular Solutions to the Nonlinear Schrödinger and the Complex Ginzburg-Landau Equations

Joel Dahne, Jordi-Lluís Figueras

We prove the existence of radial self-similar singular solutions for the mass supercritical Nonlinear Schrödinger Equation far from the critical regime and, more generally, branche…

A counterexample to Payne's nodal line conjecture with few holes

Joel Dahne, Javier Gómez-Serrano, Kimberly Hou

Payne conjectured in 1967 that the nodal line of the second Dirichlet eigenfunction must touch the boundary of the domain. In their 1997 breakthrough paper, Hoffmann-Ostenhof, Hoff…

Computation of Tight Enclosures for Laplacian Eigenvalues

Joel Dahne, Bruno Salvy

Recently, there has been interest in high-precision approximations of the first eigenvalue of the Laplace-Beltrami operator on spherical triangles for combinatorial purposes. We co…
