The mass of unimodular lattices
M. Belolipetsky, W. T. Gan
The purpose of this paper is to show how to obtain the mass of a unimodular lattice from the point of view of the Bruhat-Tits theory. This is achieved by relating the local stabili…

Automorphism groups of Riemann surfaces of genus p+1, where p is prime
M. Belolipetsky, G. A. Jones
We show that if is a compact Riemann surface of genus , where is prime, with a group of automorphisms such that for some real number …

A bound for the number of automorphisms of an arithmetic Riemann surface
M. Belolipetsky, G. A. Jones
We show that for every g > 1 there is a compact arithmetic Riemann surface of genus g with at least 4(g-1) automorphisms, and that this lower bound is attained by infinitely many g…
