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…
On surfaces of high degree with respect to the sectional genus
Ciro Ciliberto, Thomas Dedieu, Margarida Mendes Lopes
We study and classify linearly normal surfaces in , of degree and sectional genus , such that .
On the degree of the canonical map of a surface of general type
Margarida Mendes Lopes, Rita Pardini
Let X be a minimal complex surface of general type such that its image via the canonical map is a surface; we denote by d the degree of the canonical map. In this expository work,…
Semistable fibrations over an elliptic curve with only one singular fibre
Abel Castorena, Margarida Mendes Lopes, Gian Pietro Pirola
In this work we describe a construction of semistable fibrations over an elliptic curve with one unique singular fibre and we give effective examples using monodromy of curves.
Godeaux surfaces with an Enriques involution and some stable degenerations
Margarida Mendes Lopes, Rita Pardini
We give an explicit description of the Godeaux surfaces that admit an involution such that the quotient surface is birational to an Enriques surface; these surfaces give a 6-dimens…
