The Fitting subgroup of a type-definable group in a simple theory is relatively definable and nilpotent. Moreover, the Fitting subgroup of a supersimple hyperdefinable group has a normal hyperdefinable nilpotent subgroup of bounded index, and is itself of bounded index in a hyperdefinable subgroup.
Let [Formula: see text] be a class of finite groups closed under taking subgroups, homomorphic images and extensions. It is known that if normal subgroup group then the image an text]-maximal in not, general, text]. We say reduction text]-theorem holds for if, every extension (i.e. contains as subgroup), number conjugacy classes subgroups same. The implies In this paper, we prove only all are c...
Given a connected Lipschitz domain Ω we let Λ(Ω) be the subset of functions in W 2,2(Ω) whose gradient (in the sense of trace) satisfies ∇u(x)·ηx = 1 where ηx is the inward pointing unit normal to ∂Ω at x. The functional Iǫ(u) = 1 2 R
in this paper we introduce a new definition of the first non-abelian cohomology of topological groups. we relate the cohomology of a normal subgroup $n$ of a topological group $g$ and the quotient $g/n$ to the cohomology of $g$. we get the inflation-restriction exact sequence. also, we obtain a seven-term exact cohomology sequence up to dimension 2. we give an interpretation of the first non-a...
Y. Li gave a characterization of the class of finite soluble groups in which every subnormal subgroup is normal by means of NE -subgroups: a subgroup H of a group G is called an NE -subgroup of G if NG(H) ∩ H = H. We obtain a new characterization of these groups related to the local Wielandt subgroup. We also give characterizations of the classes of finite soluble groups in which every subnorma...
Let Γ be a finitely presentable pro-p group such that def(Γ) > 0. If Γ has a nontrivial finitely generated closed normal subgroup N of infinite index then def(Γ) = 1, N is a free pro-p group and Γ/N is virtually free. If π is a finitely presentable group with β (2) 1 (π) = 0 then def(π) ≤ 1, with equality only if c.d.π = 2 or π ∼= Z. (See Theorem 2.5 of [1].) The L-Betti number condition holds ...
In this paper, the notions of , q -Q-fuzzy subgroup and normal subgroup are introduced and some of their properties are investigated.
We study C?-irreducibility of inclusions reduced twisted group C?-algebras and C?-algebras. characterize in the case an inclusion arising from a normal subgroup, exhibit many new examples C?-irreducible inclusions.
objective(s) the effect of berberis vulgaris aqueous extract in hepatocarcinogenic rats was studied to investigate the apoptotic and sodium, potassium elements properties. a loss of both intracellular potassium and sodiumoccurs when apoptotic cells shrink and prior to the loss of membraneintegrity. materials and methods forty-eight sprague dawley rats were randomly divided into 2 groups, normal...
