Embeddings of finite classical groups over field extensions and their geometry
نویسندگان
چکیده
We study some embeddings of finite classical groups defined over field extensions, focusing on their geometry. The embedded groups are subgroups of classical groups lying outside the main Aschbacher classes. We concentrate on PGð8; qÞ where the embedded groups can be seen as automorphism groups of natural geometric objects: Hermitian Veroneseans, Twisted Hermitian Veroneseans and rational curves.

Classical Wavelet Transforms over Finite Fields
This article introduces a systematic study for computational aspects of classical wavelet transforms over finite fields using tools from computational harmonic analysis and also theoretical linear algebra. We present a concrete formulation for the Frobenius norm of the classical wavelet transforms over finite fields. It is shown that each vector defined over a finite field can be represented as...
متن کاملClassical wavelet systems over finite fields
This article presents an analytic approach to study admissibility conditions related to classical full wavelet systems over finite fields using tools from computational harmonic analysis and theoretical linear algebra. It is shown that for a large class of non-zero window signals (wavelets), the generated classical full wavelet systems constitute a frame whose canonical dual are classical full ...
متن کاملPolar spaces and embeddings of classical groups
Given polar spaces (V, β) and (V, Q) where V is a vector space over a field K, β a reflexive sesquilinear form and Q a quadratic form, we have associated classical isometry groups. Given a subfield F of K and an F -linear function L : K → F we can define new spaces (V, Lβ) and (V, LQ) which are polar spaces over F . The construction so described gives an embedding of the isometry groups of (V, ...
متن کاملUniversal Central Extension of Current Superalgebras
Representation as well as central extension are two of the most important concepts in the theory of Lie (super)algebras. Apart from the interest of mathematicians, the attention of physicist are also drawn to these two subjects because of the significant amount of their applications in Physics. In fact for physicists, the study of projective representations of Lie (super)algebras are very impo...
متن کاملOn the Fontaine-mazur Conjecture for Number Fields and an Analogue for Function Fields
The Fontaine-Mazur Conjecture for number fields predicts that infinite `-adic analytic groups cannot occur as the Galois groups of unramified `-extensions of number fields. We investigate the analogous question for function fields of one variable over finite fields, and then prove some special cases of both the number field and function field questions using ideas from class field theory, `-adi...
