The Number of Curves of Genus 2 with a Given Refined Humbert Invariant
Ernst Kani, Harun Kir
Let be a curve of genus 2 over an algebraically closed field . Every such curve comes equipped with a canonical quadratic form called its refined Humbert invariant.…

Constructing genus 2 curves with given refined Humbert invariants
Harun Kir
In 1994, Kani introduced an algebraic version of the Humbert invariant, known as the refined Humbert invariant. This invariant q_C is a positive definite quadratic form attached to…

The Refined Humbert Invariant for an Automorphism Group of a Genus 2 Curve
Harun Kir
The purpose of this paper is to list the refined Humbert invariants for a given automorphism group of a curve of genus 2 over an algebraically closed field with character…
