Up to isomorphism, a subobject of a constant simplicial presheaf must be constant, so that the bounded cofibration condition E7 for simplicial presheaves implies a bounded
We apply these results to characterize the trace form of a central simple algebra over such a field in terms of its determinant and signatures.. 2000 Mathematics Subject
In the preceding section we extended some “standard” pseudo-differential algebras to the pa- rameter-dependent variant, namely the algebra on a “closed” smooth manifold M with
Using the Van Kampen type theorem for the fundamen- tal crossed module, applications are given to the 2-types of mapping cones of classifying spaces of groups.. Calculations of
Using grading on this algebra we construct an analog of Cuntz algebras which gives a homotopical interpretation of..
One can find different de- scriptions (not as crossed modules) of internal categories and groupoids in groups, Mal’tsev varieties of universal algebras, congruence modular vari-
We introduce the notion of (pre)crossed module in a semiabelian category, and establish equivalences between internal reflexive graphs and precrossed modules, and between
