Counting elliptic curves of bounded Faltings height
Ruthi Hortsch
We give an asymptotic formula for the number of elliptic curves over with bounded Faltings height. Silverman has shown that the Faltings height for elliptic curves ove…
Classifications of elliptic fibrations of a singular K3 surface
Marie José Bertin, Alice Garbagnati, Ruthi Hortsch +4
We classify, up to automorphisms, the elliptic fibrations on the singular K3 surface whose transcendental lattice is isometric to .
On the canonical representation of curves in positive characteristic
Ruthi Hortsch
Given a smooth curve, the canonical representation of its automorphism group is the space of global holomorphic differential 1-forms as a representation of the automorphism group o…
A Universal Approach to Vertex Algebras
Ruthi Hortsch, Igor Kriz, Ales Pultr
We characterize vertex algebras (in a suitable sense) as algebras over a certain graded co-operad. We also discuss some examples and categorical implications of this characterizati…
