cyclic vector in nLab

A vector — hence an element of some vector space ℋ \mathcal{H} — is called cyclic with respect to the action/representation of some algebra ...

cyclic homology in nLab

Hochschild homology may be understood as the cohomology of free loop space objects (as described there). These free loop space objects are ...

cyclic set in nLab

A cyclic set is a presheaf on the cyclic category (which is often called Connes' cyclic category though it is cocyclic, with the usual contravariant confusion)

cyclic object in nLab

The concept of cyclic object is the generalization of that of cyclic sets where Set may be replaced with any other category. Cyclic objects are ...

cyclotomic space in nLab

2. Properties ... A free loop space, ℒ X \mathcal{L} X , is a cyclotomic space, where S 1 S^1 acts by rotation of loops. Let R X = holim R r ρ r * ...

The mLab - Composable adjunction

Definition: co-right pushouts are said to be closed provided that co-extensions over the cover of endofunctors are "vector space-like" from T's point of view.
