On Galois groups of prime degree polynomials with complex roots

Oz Ben-Shimol (Algebra and Discrete Mathematics, 2009)

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 ...
On some generalization of metahamiltonian groups

Semko, N.N.; Yarovaya, O.A. (Algebra and Discrete Mathematics, 2009)

Locally step groups at which all subgroups are or normal, or have Chernikov’s derived subgroup are studied.
On the quasi-primary decomposition of HK-torsion theories

Komarnytskyi, M.; Melnyk, I. (Algebra and Discrete Mathematics, 2009)

The paper is devoted to the study of quasi-primary decompositions of torsion theories in the rings which derivatives. It is shown that every HK-torsion theory of the differential noetherian completely bounded ring it is ...
On verbal subgroups of finitely generated nilpotent groups

Bier, A. (Algebra and Discrete Mathematics, 2009)

The paper concerns the problem of characterization of verbal subgroups in finitely generated nilpotent groups. We introduce the notion of verbal poverty and show that every verbally poor finitely generated nilpotent group ...
