Characterizing gonality for two-component stable curves

چکیده
It is a well-known result that stable curve of compact type over \({\mathbb {C}}\) having two components hyperelliptic if and only both are the point intersection Weierstrass for each them. With use admissible covers, we generalize this characterization in ways: curves higher gonality smooth one node; trigonal non-rational any number nodes.

Stable gonality is computable
Stable gonality is a multigraph parameter that measures the complexity of a graph. It is defined using maps to trees. Those maps, in some sense, divide the edges equally over the edges of the tree; stable gonality asks for the map with the minimum number of edges mapped to each edge of the tree. This parameter is related to treewidth, but unlike treewidth, it distinguishes multigraphs from thei...
متن کاملGonality of modular curves in characteristic p
Let k be an algebraically closed field of characteristic p. Let X(p;N) be the curve parameterizing elliptic curves with full level N structure (where p N) and full level p Igusa structure. By modular curve, we mean a quotient of any X(p;N) by any subgroup of ((Z/peZ)× × SL2(Z/NZ)) /{±1}. We prove that in any sequence of distinct modular curves over k, the k-gonality tends to infinity. This exte...
متن کاملLinear Syzygies of Curves with Prescribed Gonality
We prove two statements concerning the linear strand of the minimal free resolution of a k-gonal curve C of genus g. Firstly, we show that a general curve C of genus g of nonmaximal gonality k ≤ g+1 2 satisfies Schreyer’s Conjecture, that is, bg−k,1(C,KC) = g−k. This is a statement going beyond Green’s Conjecture and predicts that all highest order linear syzygies in the canonical embedding of ...
متن کاملE. Ballico∗ GRAPH CURVES WITH GONALITY ONE
A graph curve is a nodal curve C such that each irreducible component of C is smooth, rational and meets exactly 3 others (Bayer and Eisenbud). Here we classify the graph curves with gonality 1 with respect to balanced line bundles in the sense of L. Caporaso.
متن کاملThe Extremal Secant Conjecture for Curves of Arbitrary Gonality
We prove the Green–Lazarsfeld Secant Conjecture [GL1, Conjecture (3.4)] for extremal line bundles on curves of arbitrary gonality, subject to explicit genericity assumptions.
