Characteristic polynomials of automorphisms of hyperelliptic curves
Let α be an automorphism of a hyperelliptic curve C of genus g and let α be the automorphism induced by α on the genus-0 quotient of C by the hyperelliptic involution. Let n be the order of α and let n be the order of α. We show that the characteristic polynomial f of the automorphism α∗ of the Jacobian of C is determined by the values of n, n, and g, unless n = n, n is even, and (2g + 2)/n is ...
متن کاملDecomposing Jacobians of Curves with Extra Automorphisms
Given a fixed genus g, we would like to know the largest possible integer t such that t copies of one elliptic curve E appear in the decomposition of the Jacobian variety JX for some curve X of genus g. In this paper we find nontrivial lower bounds for t for genus up to 10. For genus 3 through 6 we demonstrate curves X such that JX∼E .
متن کاملIntersection Numbers and Automorphisms of Stable Curves
Due to the orbifold singularities, the intersection numbers on the moduli space of curves Mg,n are in general rational numbers rather than integers. We study the properties of the denominators of these intersection numbers and their relationship with the orders of automorphism groups of stable curves. In particular, we prove a conjecture of Itzykson and Zuber. We also present a conjectural mult...
متن کاملWild monodromy and automorphisms of curves
Let R be a complete discrete valuation ring of mixed characteristic (0, p) with field of fractions K containing the p-th roots of unity. This paper is concerned with semi-stable models of p-cyclic covers of the projective line C −→ PK . We start by providing a new construction of a semi-stable model of C in the case of an equidistant branch locus. If the cover is given by the Kummer equation Zp...
متن کاملAutomorphisms groups of genus 3 curves
This note mainly reproduces a sketch of two proofs ([8],[3]) of the determination of the non-trivial groups G that appear as the automorphism group of a nonhyperelliptic genus 3 curve over an algebraic closed field of characteristic zero. We display the tables obtained in these different approaches and the table given by Henn [6]too. These tables are refined in order to obtain in some situation...
