WebNote that the language L is a many-sorted rst-order pred- icate language with equality and without the symbols :, !, and 8. Now suppose that a scheme Sch is de ned by a nite geometric the- ory T = (L; I), where I is a nite set of sequents. Examples of such schemes are schemes with sets of functional, join, key, inclusion, Horn dependencies. WebAbstract We construct the derived scheme of stable sheaves on a smooth projective variety via derived moduli of finite graded modules over a graded ring. We do this by dividing the derived scheme of actions of Ciocan-Fontanine and Kapranov by a suitable algebraic gauge group.

More precisely, we show that a scheme of ﬁnite type over a ﬁeld is determined by its bounded derived category of coherent sheaves together with a collection of autoequivalences corresponding to an ample family of line bundles. gp wallingford
