On Algebraic Groups and Discontinuous Groups [PDF]
Nagoya Mathematical Journal, 1966 Let G be a connected semi-simple algebraic group defined over Q and let Γ be a discrete subgroup of GR (the subgroup of G consisting of points rational over R) such that Γ\GR is compact. The main purpose of the present paper is to prove that for a certain type of group G there exists an invariant algebraic differential from ω on G of highest degree ...

$\mathcal{T}_{M}$-Amenability of Banach Algebras [PDF]
Sahand Communications in Mathematical AnalysisWe introduce the notions of $\mathcal{T}_{M}$-amenability and $\phi$-$\mathcal{T}_{M}$-amenability. Then, we characterize $\phi$-$\mathcal{T}_{M}$-amenability in terms of $WAP$-diagonals and $\phi$-invariant means. Some concrete cases are also discussed.

Generalization of the weak amenability on various Banach algebras [PDF]
Mathematica Bohemica, 2019 The generalized notion of weak amenability, namely $(\varphi,\psi)$-weak amenability, where $\varphi,\psi$ are continuous homomorphisms on a Banach algebra ${\mathcal A}$, was introduced by Bodaghi, Eshaghi Gordji and Medghalchi (2009).

Jordan and Local Multipliers on Certain Banach Algebras are Multipliers [PDF]
Sahand Communications in Mathematical AnalysisWe prove that every continuous Jordan multiplier $T$ from a $C^*$-algebra $A$ into a Banach $A$-bimodule $X$ is a multiplier. We also characterize continuous linear maps on $C^*$-algebras and standard operator algebras determined by preserving some ...

An extension and a generalization of Dedekind's theorem [PDF]
International Journal of Group Theory, 2017 For any given finite abelian group, we give factorizations of the group determinant in the group algebra of any subgroups. The factorizations is an extension of Dedekind's theorem. The extension leads to a generalization of Dedekind's theorem.

Applied Network ScienceFor studying intrusion detection data we consider data points referring to individual IP addresses and their connections. We build networks represented by graphs associated with those data points, such that vertices in a graph are constructed to denote ...

Extensions of algebraic groups [PDF]
, 2006 Let $G$ be a connected complex algebraic group and $A$ a connected abelian algebraic group endowed with an algebraic action of $G$ by group automorphisms. In the present note we describe the abelian group $\Ext_{alg}(G,A)$ of algebraic group extensions of $G$ by $A$ in terms of a short exact sequence relating the ext-group to a relative second Lie ...

Stability and Vulnerability of Bird Flocking Behaviour: A Mathematical Analysis
Hayati Journal of Biosciences, 2019 Given a large number of birds in the flock, we mathematically investigate the mechanism the birds move in a collective behavior. We assume that each bird is able to know its position and velocity of other birds within a radius of communication.

From Context to Action: Establishing a Pre-Chain Phase Within the Cyber Kill Chain
Journal of Cybersecurity and PrivacyThe Cyber Kill Chain (CKC) is a prevalent concept in cyber defense; nevertheless, its emphasis on post-reconnaissance phases limits the capacity to foresee attacker activities outside the organizational boundary.
