Hyperelliptic odd coverings
We investigate a class of odd (ramification) coverings C → ℙ 1 where C is hyperelliptic, its Weierstrass points map to one fixed point of ℙ 1 and the...

The Complex Multiplication Method for Genus 3 Curves
We consider the problem of constructing genus 3 curves defined over the complex field with the property that their Jacobians are simple and admit... -
Uniformization of hyperelliptic curves as a systematic approach to establishing decision regions of hyperbolic signal sets
In this paper, we present a new approach to designing hyperbolic signal sets matched to groups using Whittaker’s proposal in the uniformization of...
