Finite Weyl groupoids of rank three [PDF]

open access: yesTransactions of the American Mathematical Society, 2012
We continue our study of Cartan schemes and their Weyl groupoids. The results in this paper provide an algorithm to determine connected simply connected Cartan schemes of rank three, where the real roots form a finite irreducible root system. The algorithm terminates: Up to equivalence there are exactly 55 such Cartan schemes, and the number of ...

Degenerations of toric varieties over valuation rings [PDF]

open access: yes, 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.

Lie rank in groups of finite Morley rank with solvable local subgroups [PDF]

open access: yes, 2013
We prove a general dichotomy theorem for groups of finite Morley rank with solvable local subgroups and of Pr\"ufer p-rank at least 2, leading either to some p-strong embedding, or to the Pr\"ufer p-rank being exactly ...

The theorems of Schur and Baer: a survey [PDF]

open access: yesInternational Journal of Group Theory, 2015
This paper gives a short survey of some of the known results generalizing the theorem, credited to I. Schur, that if the central factor group is finite then the derived subgroup is also finite.

Locally (Soluble-by-Finite) Groups of Finite Rank

open access: yesJournal of Algebra, 1996
The authors prove the following result: A locally (soluble-by-finite) group with all locally soluble subgroups of finite rank is (locally soluble)-by-finite and of finite rank. After they have shown that the group is of finite rank the result follows from a theorem of N. S. Chernikov.

Valuated Butler groups of finite rank [PDF]

open access: yesJournal of the Australian Mathematical Society, 2006
AbstractValuated Butler groups of finite rank are investigated. The valuated B2-groups are both epic images and pure subgroups of completely decomposable valuated groups of finite rank (Theorem 3.1). However, there are fundamental changes in the theory of Butler groups when valuations are involved. We introduce valuated B1-groups and show that they are

Groups Factorized by Pairwise Permutable Abelian Subgroups of Finite Rank [PDF]

open access: yesAdvances in Group Theory and Applications, 2016
It is proved that a group which is the product of pairwise permutable abelian subgroups of finite Prüfer rank is hyperabelian with finite Prüfer rank; in the periodic case the Sylow subgroups of such a product are described.

Separable and Low-Rank Continuous Games [PDF]

open access: yes, 2007
In this paper, we study nonzero-sum separable games, which are continuous games whose payoffs take a sum-of-products form. Included in this subclass are all finite games and polynomial games. We investigate the structure of equilibria in separable games.
