The Auslander bijections and universal extensions

Indeed, as the two trees composing the separating decomposition are isomorphic, so are their alternating embeddings and so are the two binary trees that compose the associated twin

Deux des participants m'ont dit qu'ils envisageraient volontiers d'organiser une autre école CIMPA sur un thème voisin (j'ai précisé qu'il ne fallait pas répéter les écoles, mais

To prove Theorem A, one first makes use of the Bijectivity Theorem, and deduce that the polynomial endomorphism Φ which is determined by ϕ is a polynomial au- tomorphism of

Cohomology and base change for families of coherent systems We want to prove a series of statements analogous to those in [6] for families of extensions of coherent systems instead

Using representations of quivers of type A, we define an anticyclic coop- erad in the category of triangulated categories, which is a categorification of the linear dual of

Moreover, using our result [26], we show that for tame symmetric algebras with periodic modules, the derived equivalence classification coincides with the classification up to

We propose four complementary questions to be considered when trying to classify any class of extensions of a fixed Yang-Mills-type theory S G : existence problem, obstruction

A focus on interpretation that assumes perspective in discussion with respect to the quality of „path‟ is presented; universal to all pursuits and activities it is an aspect
