On Groups with the Weak Wide Commensurable Property
Weak Wide Commensurable Property locally finite locally graded
2010/2/26
An infinite group with the weak wide commensurable property is shown to be abelian, provided that it is locally finite or locally graded or non-perfect or linear. We also investigate the properties of...
Direct Sums and the Schur Property
Schur property Banach spaces. AMS Subject Classification: 46 B 20
2010/3/4
It is a known fact that \ell1, the dual space of the null sequences c0, has the Schur property, that is, weakly convergent sequences in \ell1 are norm convergent. In this paper, we prove that if (Xa)a...
In this work it is shown that the direct product of two Meldrum groups does not satisfy the normalizer condition. It is not known yet if the same result holds true for any two HM-groups.
