Crossed modules and doi-hopf modules
Israel Journal of Mathematics, 1997The main result of this paper is that crossed modules (also known as Yetter-Drinfeld modules) are particular cases of Doi's unified Hopf modules. A generalization of crossed modules is introduced to this end, and a generalization of the Drinfeld double is defined. The latter turns out to be isomorphic to a (generalized) smash product.

On the Representation of Modules by Sheaves of Factor Modules
Canadian Mathematical Bulletin, 1971Throughout this paper we consider associative rings with unity elements. In §1 various results on the representation of rings by rings of sections of special rings are compared. In particular, it is shown that results enunciated by Dauns and Hofmann, Koh, and the present author may all be deduced from one statement, the proof of which appears in §3.

Chapter 4 examines Ellison’s use of rhythm—specifically his incorporation of polyrhythms and his application of an advanced rhythmic concept called metric modulation—to express his beliefs about virtual temporalities and social change. The chapter illustrates how Ellison often places temporal constructs, including the static time of official history ...
