Faithful homogeneous spaces over commutative groups and TST-spaces.
A set Q is a faithful homogeneous space over a commutative group iff there is a family S of mappings such that (Q,S) is a TST-space.

Fully Invariant Subgroups of -Summable Primary Abelian Groups
We present a number of results concerning fully invariant subgroups of -summable groups.
-nilpotent units of commutative group rings
Suppose is a commutative unital ring and is an abelian group. We give a general criterion only in terms of and when all normalized units in the commutative group ring are -nilpotent. This extends recent results published in [Extracta Math., 2008–2009] and [Ann. Sci. Math. Québec, 2009].
Generalizations of Cole's Systems
There are four resolvable Steiner triple systems on fifteen elements. Some generalizations of these systems are presented here.

Generalized E-algebras via λ-calculus I
An R-algebra A is called an E(R)-algebra if the canonical homomorphism from A to the endomorphism algebra of the R-module , taking any a ∈ A to the right multiplication by a, is an isomorphism of algebras. In this case is called an E(R)-module. There is a proper class of examples constructed in [4]. E(R)-algebras arise naturally in various topics of algebra. So it is not surprising that they were investigated thoroughly in the last decades; see [3, 5, 7, 8, 10, 13, 14, 15, 18, 19]. Despite...
