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 in the hull and the identity exchanging meet and join are known; imposing that be principal…

Orbit counts and twist zeta functions of weighted projective stacks over finite fields
Sajad Salami, Tanush Shaska
Let be a finite field and a vector of positive integer weights. Several finite-field counts attached to the weighted projective space $…
