An interassociate of a semigroup \((S,\cdot )\) is a semigroup \((S, *)\) such that for all \(a, b, c \in S\), \(a\cdot (b*c)=(a\cdot b) *c\) and \(a*(b\cdot c)=(a*b) \cdot c\). We investigate the bicyclic semigroup C and its interassociates. In part

We classify real Poisson structures on complex toric manifolds of type $(1,1)$ and initiate an investigation of their Poisson cohomology. For smooth toric varieties, such structures are necessarily algebraic and are homogeneous quadratic in each of t

The interassociates of the free commutative semigroup on n generators, for n > 1, are identified. For fixed n, let (S, ·) denote this semigroup. We show that every interassociate can be written in the form \((S, \ast_{\bar{k}})\), depending only on

We use chromatic numbers of hypergraphs to study the Bohr topology G # on discrete Abelian groups. In particular, if K is an infinite Abelian group of a given prime exponent, we show that G # and K # are homeomorphic iff G is the product of K and som

For an infinite abelian group G , let G # denote the Bohr topology on G . We show that G # contains a countable closed subset which is not a retract. This is a generalization of a result due to Gladdines for boolean groups.
