Linear Approximate Groups

, 2010
This is an informal announcement of results to be described and proved in detail in a paper to appear. We give various results on the structure of approximate subgroups in linear groups such as $\SL_n(k)$.

Linear Diophantine fuzzy sets over complex fuzzy information with applications in information theory

Ain Shams Engineering Journal
This article aims to link AG-groupoids and complex fuzzy set theory by constructing a method to rank complex fuzzy information, provide an alternative definition of CLDFS, and an algorithm for data encryption/decryption using AG-groupoids.

Note on quasivarieties generated by finite pointed abelian groups

Open Mathematics
We prove that a finite pointed abelian group generates a finitely axiomatizable variety that has a finite quasivariety lattice. As a consequence, we obtain that a quasivariety generated by a finite pointed abelian group has a finite basis of quasi ...

On Wielandt’s join theorem for fusion systems and localities

Forum of Mathematics, Sigma
Saturated fusion systems are categories modeling properties of conjugacy of p-elements in finite groups. It was shown by Chermak that there are group-like structures called regular localities associated to saturated fusion systems.

Closed approximate subgroups: compactness, amenability and approximate lattices

Forum of Mathematics, Sigma
We investigate properties of closed approximate subgroups of locally compact groups, with a particular interest for approximate lattices (i.e., those approximate subgroups that are discrete and have finite co-volume).

Stacky Lie groups

, 2007
Presentations of smooth symmetry groups of differentiable stacks are studied within the framework of the weak 2-category of Lie groupoids, smooth principal bibundles, and smooth biequivariant maps.

Approximate subgroups of linear groups

, 2010
We establish various results on the structure of approximate subgroups in linear groups such as SL_n(k) that were previously announced by the authors. For example, generalising a result of Helfgott (who handled the cases n = 2 and 3), we show that any ...

A prismatic classifying space

, 2018
A qualgebra $G$ is a set having two binary operations that satisfy compatibility conditions which are modeled upon a group under conjugation and multiplication. We develop a homology theory for qualgebras and describe a classifying space for it.
