The algebra of coherent algebraic sheaves
WebThe goal of this note is to spell out the (apparently well-known and intuitively clear) notion of an abelian category over a stack. In the future we will discuss the (much less evident) notion, when instead of an abelian category one considers a triangulated one. WebThe structure sheaf of a Noetherian scheme and, in particular, of an algebraic variety is coherent. Coherent algebraic sheaves are a convenient tool of investigating algebraic …

WebThe aim of this work is to give a generalization of Gabriel’s theorem for twisted sheaves over smooth varieties. We start by showing that we can reconstruct a variety X from the category Coh(X,α) of coherent α−twisted sheaves over X. This follows from the bijective correspondence between closed subsets of X and Serre subcategories of finite type of … Websome details the classical hall algebra the hall algebra of quivers and the hall algebra of coherent sheaves on smooth projective curves the last section deals with the hall algebras in ... introduction introduction to algebra introduction to equivalent algebraic prentice hall mathematics pre algebra pearson school pdf - Jul 05 2024
