Covering morphisms of crossed complexes and of cubical omega-groupoids are closed under tensor product

abstract - The excitation spectrum of atomic sodium in crossed electric and magnetic fields has been recorded.. Data for states near n = 11 are found to be in good agreement

In the general case, objects can be grasped in a continuous way. In our example, the relative orientation of the object with respect to the gripper is free around the vertical axis

In this paper, we explain how to construct reliable codes for wireless communication channels using crossed product division algebras, and we prove the optimality of the codes

Farsi, a language in which each word articulates the 900-year history of its use, was supplanted by his need to learn English, which by his comparison is a 'language of

We shall also show that relationships between groups and crossed mod- ules, involving the automorphism group, are mirrored in corresponding relationships between crossed modules

Our selection of axioms for crossed taxonomies will rely on the three following observations in the case where A is the effective taxonomy of some pointed

closed structure on Czs includes a satisfactory theory of homo- topy equivalences. But, in a similar manner to chain complexes,.. the definitions and applications

In this section we explore a direct route from m-groupoids to oo- groupoids and use it to reformulate the definitions of oo-groupoids and 00- categories. In
