On intersections of classical groups

چکیده
We describe the structure of the subgroup of the general linear group defined over a finite field that preserves two bilinear or sesquilinear forms of the same classical type, at least one of which is non-degenerate. This description underpins an algorithm to construct the intersection of two classical groups of the same type.

Intersections of Translated Algebraic Subtori
We exploit the classical correspondence between finitely generated abelian groups and abelian complex algebraic reductive groups to study the intersection theory of translated subgroups in an abelian complex algebraic reductive group, with special emphasis on intersections of (torsion) translated subtori in an algebraic torus.
متن کاملQuasi-Primary Decomposition in Modules Over Proufer Domains
In this paper we investigate decompositions of submodules in modules over a Proufer domain into intersections of quasi-primary and classical quasi-primary submodules. In particular, existence and uniqueness of quasi-primary decompositions in modules over a Proufer domain of finite character are proved. Proufer domain; primary submodule; quasi-primary submodule; classical quasi-primary; decompo...
متن کاملCollineation Groups of the Intersection of Two Classical Unitals
Kestenband proved in [12] that there are only seven pairwise non-isomorphic Hermitian intersections in the desarguesian projective plane PG 2; q of square order q. His classi®cation is based on the study of the minimal polynomials of the matrices associated with the curves and leads to results of purely combinatorial nature: in fact, two Hermitian intersections from the same class might not be...
متن کاملModeling Multiple–Vehicle Property Damage Collisions in Urban Signalized Intersections
Development of disaggregate models for estimating different property damage collision type frequencies in urban intersections has rarely been studied, particularly in Iran. It seems very little research work being implemented for studying the effect factors on collision type frequency at intersections. The main objective of this paper is to develop suitable statistical models to predict types o...
متن کاملIntersecting Two Classical Groups
A new algorithm is presented to compute the algebra of adjoints associated to a pair of forms on a common finite vector space. This algebra is used in several recent and ongoing projects to study central products, intersections of classical groups, and automorphism groups. The implementation of the new algorithms in Magma greatly outperforms its predecessor and hence, in restricted yet importan...
