Global Frobenius liftability II: surfaces and Fano threefolds

چکیده
In this article, a sequel to Global Frobenius Liftability I (math:1708:03777v2), we continue the development of comprehensive theory liftings modulo $p^2$. We study compatibility divisors and closed subschemes with liftings, blow-ups, descent under quotients by some group actions, stability base change, properties associated F-splittings. Consequently, characterise liftable surfaces Fano threefolds, confirming conjecture stated in our previous paper.

Projective Degenerations of K Surfaces Gaussian Maps and Fano Threefolds
In this article we exhibit certain projective degenerations of smoothK surfaces of degree g in P whose Picard group is generated by the hyperplane class to a union of two rational normal scrolls and also to a union of planes As a consequence we prove that the general hyperplane section of such K surfaces has a corank one Gaussian map if g or g We also prove that the general such hyperplane sect...
متن کاملCanonical Toric Fano Threefolds
An inductive approach to classifying all toric Fano varieties is given. As an application of this technique, we present a classification of the toric Fano threefolds with at worst canonical singularities. Up to isomorphism, there are 674,688 such varieties.
متن کاملHyperelliptic and Trigonal Fano Threefolds
We classify Fano 3-folds with canonical Gorenstein singularities whose anticanonical linear system has no base points but does not give an embedding, and we classify anticanonically embedded Fano 3-folds with canonical Gorenstein singularities which are not the intersection of quadrics.
متن کاملSimple Helices on Fano Threefolds
Building on the work of Nogin [17], we prove that the braid group B4 acts transitively on full exceptional collections of vector bundles on Fano threefolds with b2 = 1 and b3 = 0. Equivalently, this group acts transitively on the set of simple helices (considered up to a shift in the derived category) on such a Fano threefold. We also prove that on threefolds with b2 = 1 and very ample anticano...
متن کاملLow Codimension Fano–enriques Threefolds
Introduction In the 1970s, Reid introduced the graded rings method for the explicit classification of surfaces, which he used to produce a list of 95 K3 quasi-smooth hypersurfaces in weighted projective spaces (which were proved to be the only ones). Later, Fletcher used this method to create more lists of different weighted complete intersections. From the K3 surfaces he developed two lists of...
