✦ Synopsis

For any Set-endofunctor F, the category SetF of F-coalgebras has preimages, i.e. pullbacks along an injective map. If F preserves preimages, then SetF is distributive, and the converse holds, whenever SetF has ÿnite products.

In this article we deÿned and studied quasi-ÿnite comodules, the cohom functors for coalgebras over rings. Linear functors between categories of comodules are also investigated and it is proved that good enough linear functors are nothing but a cotensor functor. Our main result of this work characte

The Cirel'son bound for the EPR experimental set-up provides a test of the distributivity of the observable algebra and is thus satisfied by Jordan algebras and distributive Segal algebras. By means of nondistributive algebras, the Cirel'son bound may be violated and the Rastall limit attained. It i

Given a Newtonian coalgebra we associate to it a chain complex. The homology groups of this Newtonian chain complex are computed for two important Newtonian coalgebras arising in the study of flag vectors of polytopes: R a, b and R c, d . The homology of R a, b corresponds to the homology of the bou
