Logics of Finite Hankel Rank [PDF]
, 2015 We discuss the Feferman-Vaught Theorem in the setting of abstract model theory for finite structures. We look at sum-like and product-like binary operations on finite structures and their Hankel matrices.

Finite rank and pseudofinite groups [PDF]
Journal of Group Theory, 2018 It is proven that an infinite finitely generated group cannot be elementarily equivalent to an ultraproduct of finite groups of a given Pr\"ufer rank.

Colloquium Mathematicum, 1997 This paper contains a survey of a special class of examples of systems constructed in ergodic theory. Its aim is to gather definitions related to notions of rank, to describe the relations between them, and to show how these notions apply to some classical systems.

Publicacions Matemàtiques, 2021 We study the structure of groups of finite (Prufer) rank in a very wide class of groups and also of central extensions of such groups. As a result we are able to improve, often substantially, on a number of known numerical bounds, in particular on bounds for the rank (resp.

The BEL-rank of finite semifields [PDF]
Designs, Codes and Cryptography, 2016 In this article we introduce the notion of the BEL-rank of a finite semifield, prove that it is an invariant for the isotopism classes, and give geometric and algebraic interpretations of this new invariant. Moreover, we describe an efficient method for calculating the BEL-rank, and present computational results for all known small semifields.

Vector bundles of finite rank on complete intersections of finite codimension in ind-Grassmannians
Complex Manifolds, 2015 In this article we establish an analogue of the Barth-Van de Ven-Tyurin-Sato theorem.We prove that a finite rank vector bundle on a complete intersection of finite codimension in a linear ind-Grassmannian is isomorphic to a direct sum of line bundles.

Finiteness results for subgroups of finite extensions [PDF]
, 2014 We discuss in the context of finite extensions two classical theorems of Takahasi and Howson on subgroups of free groups. We provide bounds for the rank of the intersection of subgroups within classes of groups such as virtually free groups, virtually ...

Degenerations of toric varieties over valuation rings [PDF]
, 2016 We develop a theory of multi-stage degenerations of toric varieties over finite rank valuation rings, extending the Mumford--Gubler theory in rank one.

Surfaces of Finite Domain Rank [PDF]
Proceedings of the American Mathematical Society, 1970 In this paper it is shown that a surface has finite domain rank if and only if it is homeomorphic to a domain of a compact or closed surface.
