Orbits and Fields of Definition for Graded Keller Maps

Kyle Kistner, Tanush Shaska

We classify graded Keller maps by the signature of their weight vectors and address which hyperbolic weights support counterexamples and how the nonempty loci are stratified. We co…

Hulls, linear equivalence, and weighted superelliptic codes

Jurgen Mezinaj, Tanush Shaska

The containment of the code of the meet $G \land A$ in the hull and the identity $G \lor A - D = K - G \land A$ exchanging meet and join are known; imposing that $G \land A$ be principal…

Orbit counts and twist zeta functions of weighted projective stacks over finite fields

Sajad Salami, Tanush Shaska

Let $F_{q}$ be a finite field and $w = (w_{0}, \dots, w_{n})$ a vector of positive integer weights. Several finite-field counts attached to the weighted projective space $…

Subvarieties of the hyperelliptic moduli determined by group actions

T. Shaska

Let $H_{g}$ be the moduli space of genus $g$ hyperelliptic curves. In this note, we study the locus $L$ in $H_{g}$ of curves admitting a $G$ -action of given…

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…

Hyperelliptic curves of genus 3 with prescribed automorphism group

J. Gutierrez, D. Sevilla, T. Shaska

We study genus 3 hyperelliptic curves which have an extra involution. The locus $Ł_{3}$ of these curves is a 3-dimensional subvariety in the genus 3 hyperelliptic moduli $\H_3$. We f…
