Torsion Free Sheaves on Cuspidal Curves
Dan Avritzer, Flaviana Andrea Ribeiro, Renato Vidal Martins
We study torsion free sheaves on integral projective curves with at most ordinary cusps as singularities. Adjusting Seshadri's structure from the nodal case to this one, we describ…
Moduli spaces of quadratic complexes and their singular surfaces
D. Avritzer, H. Lange
We construct the coarse moduli space $\cM_{qc}(σ)$ of quadratic line complexes with a fixed Segre symbol as well as the moduli space $\cM_{ss}(σ)$ of the corresponding singular…
The moduli spaces of hyperelliptic curves and binary forms
Dan Avritzer, Herbert Lange
There is a canonical isomorphism between the coarse moduli spaces of somooth hyperelliptic curves of genus g and binary forms of degree 2g+2 with nonzero discriminant. In this pape…
Curves of genus 2 and Desargues configurations
Dan Avritzer, Herbert Lange
We study the moduli space M_D of Desargues configurations and how to define a holomorphic map from M_D to M^b_6 the moduli space of stable binary forms of degree 6. The constructio…
