Highest Cusped Waves for the Burgers-Hilbert equation

In this paper we prove the existence of a periodic highest, cusped, traveling wave solution for the Burgers-Hilbert equation f t + ff x = H [ f ] and give its asymptotic behaviour at 0. The proof

A toy Neumann analogue of the nodal line conjecture

We introduce an analogue of Payne’s nodal line conjecture, which asserts that the nodal (zero) set of any eigenfunction associated with the second eigenvalue of the Dirichlet Laplacian on a bounded

On the nodal lines of second eigenfunctions of the fixed membrane problem

A well-known conjecture about the second eigenfunction of a bounded domain in ℝ2 states that the nodal line has to intersect the boundary in exactly two points. We give sufficient conditions on the

On nodal line of the second eigenfunction of the Laplacian over concave domains in ℝ2

In this note, the Payne’s conjecture from convex domains to concave domains is generalized. It is shown that the nodal line N of the second eigenfunction of the Laplacian over some simply connected

Nodal line estimates for the second Dirichlet eigenfunction

We study the nodal curves of low energy Dirichlet eigenfunctions in generalized curvilinear quadrilaterals. The techniques can be seen as a generalization of the tools developed by Grieser-Jerison in

Nodal lines of eigenfunctions of the fixed membrane problem in general convex domains

We describe the boundary behavior of the nodal lines of eigenfunctions of the fixed membrane problem in convex, possibly nonsmooth, domains. This result is applied to the proof of Payne’s conjecture

Reviving the Method of Particular Solutions

It is explained why Fox, Henrici, and Moler's formulation of this method breaks down when applied to regions that are insufficiently simple and a modification is proposed that avoids these difficulties.

Any three eigenvalues do not determine a triangle

On the second eigenfunctions of the Laplacian in R2

A conjecture about the nodal line of a second eigenfunction states that the nodal line of a second eigenfunction divides the domain Ω by intersecting with the boundary of Ω transversely, where Ω is a

Computation of Tight Enclosures for Laplacian Eigenvalues

Improved and certified enclosures to improved and certified eigenvalues of the first eigenvalue of the Laplace-Beltrami operator on spherical triangles for combinatorial purposes are computed.

Closed nodal surfaces for simply connected domains in higher dimensions

We give an example of a domain in dimension $N \geq 3$, homeomorphic to a ball and with analytic boundary, for which the second eigenvalue of the Dirichlet Laplacian has an eigenfunction with a
