Units of p-power order in principal p-blocks of p-constrained groups
نویسنده
چکیده
Let G be a finite group having a normal p-subgroup N that contains its centralizer CG(N), and let R be a p-adic ring. It is shown that any finite p-group of units of augmentation one in RG which normalizes N is conjugate to a subgroup of G by a unit of RG, and if it centralizes N it is even contained in N .

Solving Security Constrained Unit Commitment by Particle Swarm Optimization
The issue of unit commitment is one of the most important economic plans in power system. In modern and traditional power systems, in addition to being economical of the planning, the issue of security in unit operation is also of great importance. Hence power system operation confronts units’ participation and input considering network security constrains. The issue of units’ participation is ...
متن کاملFinite groups with $X$-quasipermutable subgroups of prime power order
Let $H$, $L$ and $X$ be subgroups of a finite group$G$. Then $H$ is said to be $X$-permutable with $L$ if for some$xin X$ we have $AL^{x}=L^{x}A$. We say that $H$ is emph{$X$-quasipermutable } (emph{$X_{S}$-quasipermutable}, respectively) in $G$ provided $G$ has a subgroup$B$ such that $G=N_{G}(H)B$ and $H$ $X$-permutes with $B$ and with all subgroups (with all Sylowsubgroups, respectively) $...

In solving the electrical power systems economic dispatch (ED) problems, the goal is to schedule the committed generating units outputs so as to meet the required load demand at the minimum operating cost while satisfying all units and system equality and inequality constraints. This paper presents a different approach to economic dispatch problems with particle swarm optimization (PSO) techniq...
متن کاملOn the Navarro-willems Conjecture for Blocks of Finite Groups
Let G be a finite group. For a prime p and a p-block B of G, we denote by Irr(B) the set of complex irreducible characters of G that belong to B. It was conjectured by Navarro and Willems [NW] that if for blocks Bp and Bq of G at different primes p, q we have an equality Irr(Bp) = Irr(Bq) then |Irr(Bp)| = 1. But then the first author of the present article found that the extension group 6.A7 of...
