supersoluble conditions and transfer control
نویسندگان
چکیده
in this paper we give a new condition for a sylow $p$-subgroup of a finite group to control transfer. then it is deduced a characteri-zation of supersoluble groups that can be seen as a generalization of the well known result concerning the supersolubility of finite groups with cyclic sylow subgroups. moreover a condition for a normal embedding of a strongly closed $p$-subgroup is given. these results make use of the properties of $g$-chains and $phi$-chains.

Supersoluble Groups
We shall term a group G supersoluble if every homomorphic image H9*l of G contains a cyclic normal subgroup different from 1. Supersoluble groups with maximum condition, in particular finite supersoluble groups, have been investigated by various authors: Hirsch, Ore, Zappa and more recently Huppert and Wielandt. In the present note we want to establish the close connection between supersoluble ...
متن کاملA Class of Generalized Supersoluble Groups
This paper is devoted to the study of groups G in the universe cL̄ of all radical locally finite groups with min-p for all primes p such that every δ-chief factor of G is either a cyclic group of prime order or a quasicyclic group. We show that within the universe cL̄ this class of groups behaves very much as the class of finite supersoluble groups.
متن کاملLanguages Recognized by Finite Supersoluble Groups
In this paper, we give two descriptions of the languages recognized by finite supersoluble groups. We first show that such a language belongs to the Boolean algebra generated by the modular products of elementary commutative languages. An elementary commutative language is defined by a condition specifying the number of occurrences of each letter in its words, modulo some fixed integer. Our sec...
متن کاملControl and Management of Vector-Borne Diseases in Disaster Conditions
Disasters are a set of unexpected situations that occur as a result of natural misadventure or human manipulations. Depending on the type, time, and location of the events, the insect population causing vector-borne diseases is affected, which may eventually lead to widespread epidemics. Parasitic diseases such as malaria, leishmaniosis, arboviral diseases such as dengue fever, West Nile enceph...
متن کاملConditions of transfer and quality of food.
Many factors contribute to the production of safe foods of animal origin. Initiatives for an integrated approach to food safety recognise the importance of optimising transportation conditions to ensure on-farm interventions are preserved. Physical, microbial, and environmental hazards during the transportation process may adversely affect the safety and quality of meat, poultry, and egg produc...
متن کاملTransfer of boundary conditions for
In this paper, the concept of Abramov's method for transferring boundary conditions posed for regular ordinary diierential equations is applied to index 1 DAEs. Having discussed the reduction of inhomogeneous problems to homogeneous ones and analyzed the underlying ideas of Abramov's method, we consider boundary value problems for index 1 linear DAEs both with constant and varying leading matri...
