Rational conic fibrations sectional genus two / A. Lanteri, R. Mallavibarrena. - In: ADVANCES IN GEOMETRY. - ISSN 1615-715X. - 21:2(2021 May), pp. 281-292. [10.1515/advgeom-2020-0022]
Abstract:
Polarized rational surfaces (X, L) of sectional genus two ruled in conics are studied. When they are
not minimal, they are described as the blow-up of _1 at some points lying on distinct fibers. Ampleness and
very ampleness of L are studied in terms of their location. When L is very ample and there is a line contained
in X and transverse to the fibers, the conic fibrations (X, L) are classified and a related property concerned
with the inflectional locus is discussed.
