Cohomology and Obstructions: Commutative Algebras
Associated with each of the classical cohomology theories in algebra has been a theory relating H (H as classically numbered) to obstructions to non-singular extensions and H with coefficients in a “center” to the non-singular extension theory (see [Eilenberg & MacLane (1947), Hochschild (1947), Hochschild (1954), MacLane (1958), Shukla (1961), Harrison (1962)]). In this paper we carry out the ...
متن کاملExtending Obstructions to Noncommutative Functorial Spectra
Any functor from the category of C*-algebras to the category of locales that assigns to each commutative C*-algebra its Gelfand spectrum must be trivial on algebras of n-by-n matrices for n ≥ 3. This obstruction also applies to other spectra such as those named after Zariski, Stone, and Pierce. We extend these no-go results to functors with values in (ringed) topological spaces, (ringed) topose...
متن کاملNonabelian Cohomology and Obstructions, following Wojtkowiak [2]
Let D be a small category. We define a variety of cohomology objects. Each starts with a functor to a category of " coefficents, " and produces a different sort of object as output. The coefficient categories are: sets Set, groups Gp, abelian groups Ab, and " bands " HGp, that is, the category whose objects are groups and whose morphisms are conjugacy classes of homomorphisms. Let S : D → Set b...
متن کاملTwisted Actions and Obstructions in Group Cohomology
This article is intended to answer the question “Why do you guys always want to twist everything?” We review the various ways in which twists, twisted actions and twisted crossed products arise, and then discuss some cohomological obstructions to the existence and triviality of twisted actions. Our review begins with the classical problems of classifying group extensions and irreducible unitary...
متن کاملCohomology operations and algebraic geometry
This manuscript is based on a ten hours series of seminars I delivered in August of 2003 at the Nagoya Institute of Technology as part of the workshop on homotopy theory organized by Norihiko Minami and following the Kinosaki conference in honor of Goro Nishida. One of the most striking applications of homotopy theory in “exotic” contexes is Voevodsky’s proof of the Milnor Conjecture. This conj...
