چکیده
The purpose of this paper is to extend the results in [11] in the case of del Pezzo fibrations of degree 1. To this end we investigate the anticanonical linear systems of del Pezzo surfaces of degree 1. We then classify all possible effective anticanonical divisors on Gorenstein del Pezzo surfaces of degree 1 with canonical singularities.

A Note on Del Pezzo Fibrations of Degree 1
Let O be a discrete valuation ring with residue field k of characteristic 0. We denote by K the quotient field of O. A model of a variety XK defined over K is a flat scheme X defined over Spec O whose generic fiber is isomorphic to XK . Fano fibrations are models of smooth Fano varieties defined over K. In particular, del Pezzo fibrations of degree d are models of smooth del Pezzo surfaces of d...
متن کاملOn a Rigidity Criterion for Del Pezzo Fibrations over P
We discuss the rigidity problem for Mori fibrations on del Pezzo surfaces of degree 1, 2 and 3 over P and formulate the following conjecture: a del Pezzo fibration V/P is rigid iff for any linear system without fixed components its quasi-effective and adjunction thresholds coincide. We prove the ”only if” part of this conjecture. Birational rigidity is one of the main notions in higher-dimensio...
متن کاملOn Birational Geometry of Singular Del Pezzo Fibrations
In this article, birational geometry of singular 3-fold del Pezzo fibrations of degree two is considered. After reviewing the very limited literature on this topic, I investigate three aspects of research closely related to this problem. First, I consider a known conjecture about birational rigidity that holds for smooth models and is conjectured in general. I provide a counterexample for the s...
متن کاملNonrational Del Pezzo Fibrations
In this paper we study cubic del Pezzo fibrations f : X → P such that the 3-fold X is smooth and rkPic(X) = 2. These are the examples of smooth 3-fold Mori fibre spaces. The 3-fold X is a divisor in the linear system |3M + nL| on the rational scroll Proj(⊕ i=1 OP1(di)), where n and di are integers, d1 ≥ d2 ≥ d3 ≥ d4 = 0, M is a tautological line bundle, and L is a fibre of the projection to P. ...
متن کاملOn the Arithmetic of Del Pezzo Surfaces of Degree 2
Del Pezzo surfaces are smooth projective surfaces, isomorphic over the algebraic closure of the base ,eld to P P or the blow-up of P in up to eight points in general position. In the latter case the del Pezzo surface has degree equal to 9 minus the number of points in the blow-up. The arithmetic of del Pezzo surfaces over number ,elds is an active area of investigation. It is known that the Has...
