The research is motivated by a construction of groups oscillating growth Kassabov and Pak [25] description possible functions finitely generated associative algebras Bell Zelmanov [9]. In this paper we address both, the question in case Lie algebras, Kurosh problem, because our examples restricted have nil p-mapping, which an analogue nillity for or periodicity groups. Namely, any field positiv...
in a pot experiment the effect of water stress on the proteins and proline amino acid content of jam, kurosh, pirooz chickpea cultivars (cicer arientinum) were evaluated using a complete block design with factorial treatments inducing cultivars and watering periods, three, six and nine day intervals in three replications. soluble protein and free proline content of the leaf and the root were me...

Fault diagnosis is a complex and fuzzy cognitive process, and soft computing methods and technologies based on Neural Networks (NN) and Fuzzy Logic (FL), have shown great potential in the development of Decision Support Systems (DSS). Dealing with expert (human) knowledge consideration, Computer Aided Diagnosis (CAD) dilemma is one of the most interesting, but also one of the most difficult pro...
The elliptic elements of M, each with two conjugate complex fixed points, are precisely the conjugates of nontrivial powers of A and B. The parabolic elements, each with a single real fixed point, are precisely the conjugates of nontrivial powers of C = AB: z ~ z + 1. The remaining nontrivial elements of M are hyperbolic, each with two real fixed points. A subgroup S of M is torsionfree (and th...
Let (Gi | i ∈ I) be a family of groups, let F be a free group, and let G = F ∗ ∗ i∈I Gi, the free product of F and all the Gi. Let F denote the set of all finitely generated subgroups H of G which have the property that, for each g ∈ G and each i ∈ I, H∩Ggi = {1}. By the Kurosh Subgroup Theorem, every element of F is a free group. For each free group H, the reduced rank of H, denoted r̄(H), is d...
Generalizations of the series exp and log to noncommutative non-associative and other types of algebras were regarded by M. Lazard, and recently by V. Drensky and L. Gerritzen. There is a unique power series exp(x) in one non-associative variable x such that exp(x) exp(x) = exp(2x), exp ′ (0) = 1. We call the unique series H = H(x, y) in two non-associative variables satisfying exp(H) = exp(x) ...
not null-homotopic such that [Z,X] [Z, f ] → [Z, Y ] is constant. For any X ′ ⊂ X with fewer than κ cells there exists X ′ → Z → X ′ = 1X′ , from which we may conclude that [X ′, X] [X ′, f ] → [X ′, Y ] is constant and in particular that f |X ′ is null-homotopic. Let H be the homotopy category obtained from T . Its objects are the objects of T , its maps are homotopy-classes of maps. The theor...
In this note we shall investigate a topological version of the problem of Kurosh: “Is any algebraic algebra locally finite?” Kaplansky’s theorem concerning the local nilpotence of nil PI-algebras is well-known. We will prove a generalization of Kaplansky’s theorem to the class of locally compact rings. We use in the proof a theorem of A. I. Shirshov [8] concerning the height of a finitely gener...
Introduction Never in the history of mathematics has a mathematical theory been the object of such vociferous vituperation as lattice theory. Dedekind, Jónsson, Kurosh, Malcev, Ore, von Neumann, Tarski, and most prominently Garrett Birkhoff have contributed a new vision of mathematics, a vision that has been cursed by a conjunction of misunderstandings, resentment, and raw prejudice. The hostil...
