The parity of theta characteristics is preserved by infinitesimal deformations
Margarida Mendes Lopes, Rita Pardini, Roberto Pignatelli
In this note, given a family of relative dimension one over a smooth curve, we determine the parity of the restriction of a relative theta characteristic to an arbitrary multiple o…
Surfaces with canonical map of odd degree
Margarida Mendes Lopes, Rita Pardini, Roberto Pignatelli
Let be a smooth complex minimal surface of general type with whose canonical map is generically finite of odd degree onto a surface . We assume th…
Half canonical rings of Gorenstein spin curves of genus two
Stephen Coughlan, Marco Franciosi, Rita Pardini +1
We introduce the notion of generalised Gorenstein spin structure on a curve and we give an explicit description of the associated section ring for curves of genus two with ample ca…
A footnote to a theorem of Kawamata
Margarida Mendes Lopes, Rita Pardini, Sofia Tirabassi
Kawamata has shown that the quasi-Albanese map of a quasi-projective variety with log-irregularity equal to the dimension and log-Kodaira dimension 0 is birational. In this note we…
Degeneration of Hodge structures on I-surfaces
Stephen Coughlan, Marco Franciosi, Rita Pardini +1
Work of Green, Griffiths, Laza, and Robles suggests that the moduli space of (smoothable) stable surfaces should admit a natural stratification defined via Hodge theoretic data. In…
Effective characterization of quasi-abelian surfaces
Margarida Mendes Lopes, Rita Pardini, Sofia Tirabassi
Let V be a smooth quasi-projective complex surface such that the three first logarithmic plurigenera are equal to 1 and the logarithmic irregularity is equal to 2. We prove that th…
