Abundance for slc surfaces over arbitrary fields

چکیده
We prove the abundance conjecture for projective slc surfaces over arbitrary fields of positive characteristic. The proof relies on lc abritrary fields, proved by Tanaka, and technique Hacon Xu to descend semi-ampleness from normalization. also present applications dlt threefold pairs, mixed characteristic families surfaces.

Surfaces over Arbitrary Triangulations
Recently in [7). a new multivariate B-spline scheme based on blending functions and control vertices was developed . This surface scheme allows CIo-1-continuous piecewise polynomial surfaces of degree k over arbitrary triangulations to be modelled . Actually, piecewise polynomial surfaces over a refined triangulation are produced given an arbitrary triangulation . The scheme exhibits both affin...
متن کاملMultiplication over Arbitrary Fields
We prove a lower bound of 52n2 3n for the rank of n n–matrix multiplication over an arbitrary field. Similar bounds hold for the rank of the multiplication in noncommutative division algebras and for the multiplication of upper triangular matrices.
متن کاملQuadratic Forms over Arbitrary Fields
Introduction. Witt [5] proved that two binary or ternary quadratic forms, over an arbitrary field (of characteristic not 2) are equivalent if and only if they have the same determinant and Hasse invariant. His proof is brief and elegant but uses a lot of the theory of simple algebras. The purpose of this note is to make this fundamental theorem more accessible by giving a short proof using only...
متن کاملAlgebraic Groups over Arbitrary Fields
In this chapter, we study algebraic groups, especially nonsplit reductive groups, over arbitrary fields. The algebraic groups over a field k that become isomorphic to a fixed algebraic group over kal are classified by a certain cohomology group. In the first section, we explain this, and discuss what is known about the cohomology groups. Over an algebraically closed field, the classical semisim...
