A simple characterization of sets satisfying the Central Sets Theorem
Central subsets of a discrete semigroup S have very strong combinatorial properties which are a consequence of the Central Sets Theorem. Call a set a C-set if it satisfies the conclusion of the Central Sets Theorem. We obtain here a reasonably simple characterization of C-sets in an arbitrary discrete semigroup.
متن کاملSmall Sets Satisfying the Central Sets Theorem
The Central Sets Theorem is a powerful theorem, one of whose consequences is that any central set in N contains solutions to any partition regular system of homogeneous linear equations. Since at least one set in any finite partition of N must be central, any of the consequences of the Central Sets Theorem must be valid for any partition of N. It is a result of Beiglböck, Bergelson, Downarowicz...
متن کاملPolycube Unfoldings Satisfying Conway’s Criterion
We prove that some classes of polycubes admit vertex and edge unfoldings that tile the plane. Surprisingly, every such polycube found has an unfolding satisfying Conway’s criterion and it remains open whether all polycubes have edge unfoldings satisfying Conway’s criterion.

15 صفحه اولTests for Gene Clusters Satisfying the Generalized Adjacency Criterion
We study a parametrized definition of gene clusters that permits control over the trade-off between increasing gene content versus conserving gene order within a cluster. This is based on the notion of generalized adjacency, which is the property shared by any two genes no farther apart, in the linear order of a chromosome, than a fixed threshold parameter θ. Then a cluster in two or more genom...
