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…
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…
Moduli of real pointed quartic curves
Sander Rieken
We describe a natural open stratum in the moduli space of smooth real pointed quartic curves in the projective plane. This stratum consists of real isomorphism classes of pairs $(C…
