Specifically, we show some sufficient conditions for the Frattini subalgebra to be an ideal and find an example where the Frattini subalgebra fails to be an ideal. 2009-01-01T00:00:00Z Commutative dimonoids Zhuchok, A.V. http://dspace.nbuv.gov.ua:80/handle/123456789/154613 2019-06-15T22:30:22Z 2009-01-01T00:00:00Z Commutative dimonoids Zhuchok, A.V. We present some congruence on the dimonoid with a commutative operation and use it to obtain a decomposition of a commutative dimonoid. 2009-01-01T00:00:00Z On some generalization of metahamiltonian groups Semko, N.N.

Locally step groups at which all subgroups are or normal, or have Chernikov’s derived subgroup are studied. 2009-01-01T00:00:00Z On Galois groups of prime degree polynomials with complex roots Oz Ben-Shimol http://dspace.nbuv.gov.ua:80/handle/123456789/154610 2019-06-15T22:28:12Z 2009-01-01T00:00:00Z On Galois groups of prime degree polynomials with complex roots Oz Ben-Shimol Let f be an irreducible polynomial of prime degree p≥5 over Q, with precisely k pairs of complex roots. Using a result of Jens Hochsmann (1999), show that if p≥4k+1 then Gal(f/Q) is isomorphic to Ap or Sp. This improves the algorithm for computing the Galois group of an irreducible polynomial of prime degree, introduced by A. Bialostocki and T. Shaska. If such a polynomial f is solvable by radicals then its Galois group is a Frobenius group of degree p. Conversely, any Frobenius group of degree p and of even order, can be realized as the Galois group of an irreducible polynomial of degree p over Q having complex roots. 2009-01-01T00:00:00Z
