Characterizing Curves by Their Odd Theta-characteristics
Consider, for every g ≥ 4, a non-singular, complex, canonical curve of genus g, that is, a curve X embedded in P by its complete canonical series |ωX |. Each such a curve possesses 2 2g line bundles L of degree g − 1 such that L = ωX , the theta-characteristics of X, and precisely Ng := ( 2 2 ) of them are odd (i.e. h(X,L) is odd). To a non-zero section σ of a theta-characteristic one associate...
متن کاملTheta - Characteristics on Algebraic Curves
The theory of theta-characteristics is developed algebraically, so that it may be applied to possibly singular and/or reducible algebraic curves. The configuration of theta-characteristics on a curve is described in terms of its singularities, with applications to the geometry of plane quartic curves and the problem of Appolonius. Some results on Gorenstein local rings are appended. 0. Introduc...
متن کاملOn Modular Properties of Odd Theta-characteristics
A general canonical curve X ⊂ P determines a finite set θ(X) of hyperplanes that are tangent to X at g − 1 points. Such a set is in bijective correspondence with the set of odd theta-characteristics of X. We generalize the definition of θ(X) to certain singular curves (including Deligne-Mumford stable curves) in a way that is compatible with degenerations. We give the explicit description of θ(...
متن کاملReal theta-characteristics on real projective curves
Here we prove the existence of non-locally free real theta-characteristics on any real reduced projective curve.
متن کاملTheta Characteristics and Their Moduli
Theta characteristics appeared for the first time in the context of characteristic theory of odd and even theta functions in the papers of Göpel [Go] and Rosenhain [Ro] on Jacobi’s inversion formula for genus 2. They were initially considered in connection with Riemann’s bilinear addition relation between the degree two monomials in theta functions with characteristics. Later, in order to syste...
