Variations of Weyl's tube formula

Annegret Burtscher, Gert Heckman

In 1939 Weyl showed that the volume of spherical tubes around compact submanifolds M of Euclidean space depends solely on the induced Riemannian metric on M. Can this intrinsic nat…

Hyperbolic Geometry and Moduli of Real Curves of Genus Three

Gert Heckman, Sander Rieken

The moduli space of smooth real plane quartic curves consists of six connected components. We prove that each of these components admits a real hyperbolic structure. These connecte…

Angular Momenta of Relative Equilibrium Motions and Real Moment Map Geometry

Gert Heckman, Lei Zhao

Chenciner and Jimenez Perez showed that the range of the spectra of the angular momenta of all the rigid motions of a fixed central configuration in a general Euclidean space form…

Two Lorentzian Lattices

Gert Heckman, Sander Rieken

We prove a conjecture formulated by the first author, which in turn provides a good deal of evidence for the monstrous proposal of Daniel Allcock.

An Odd Presentation of

Gert Heckman, Sander Rieken

The Weyl group has an odd presentation due to Christopher Simons as factor group of the Coxeter group on the Petersen graph by deflation of the free hexagons. The…

Matrix Valued Orthogonal Polynomials for Gelfand Pairs of Rank One

Gert Heckman, Maarten van Pruijssen

In this paper we study matrix valued orthogonal polynomials of one variable associated with a compact connected Gelfand pair (G,K) of rank one, as a generalization of earlier work…
