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 the subloci of the moduli space of curves having a d…
Thetanulls of cyclic curves of small genus
E. Previato, T. Shaska, G. S. Wijesiri
We study relations among the classical thetanulls of cyclic curves, namely curves (of genus ) with an automorphism such that generates a norma…
Theta functions and algebraic curves with automorphisms
T. Shaska, G. S. Wijesiri
Let $\X$ be an irreducible, smooth, projective curve of genus defined over the complex field $\C.$ Then there is a covering $π: \X \longrightarrow ¶^1,$ where deno…
Codes over rings of size and lattices over imaginary quadratic fields
T. Shaska, C. Shor, G. Wijesiri
Let be a square-free integer congruent to 3 mod 4 and the ring of integers of the imaginary quadratic field . Codes over rings d…
Codes over rings of size four, Hermitian lattices, and corresponding theta functions
T. Shaska, G. S. Wijesiri
Let be an imaginary quadratic field with ring of integers , where is a square free integer such that and be a linea…
