Degree 4 coverings of elliptic curves by genus 2 curves

T. Shaska, G. Wijesiri, S. Wolf +1

Genus two curves covering elliptic curves have been the object of study of many articles. For a fixed degree $n$ the subloci of the moduli space $M_{2}$ of curves having a d…

Theta functions and algebraic curves with automorphisms

T. Shaska, G. S. Wijesiri

Let $\X$ be an irreducible, smooth, projective curve of genus $g \geq 2$ defined over the complex field $\C.$ Then there is a covering $π: \X \longrightarrow ¶^1,$ where $¶^{1}$ deno…

Codes over rings of size $p^{2}$ and lattices over imaginary quadratic fields

T. Shaska, C. Shor, G. Wijesiri

Let $ℓ > 0$ be a square-free integer congruent to 3 mod 4 and $Ø_{K}$ the ring of integers of the imaginary quadratic field $K = Q (- ℓ)$ . Codes $C$ over rings $Ø_{K} / p Ø_{K}$ d…
