Tilting Bundles on Orders on P
We introduce a class of orders on P called Geigle-Lenzing orders and show that they have tilting bundles. Moreover we show that their module categories are equivalent to the categories of coherent sheaves on Geigle-Lenzing spaces introduced in [HIMO].
متن کاملTilting Selfinjective Algebras and Gorenstein Orders
BY Rickard's fundamental theorem [8], the rings which are derived equivalent to a ring A are precisely the endomorphism rings of tilting complexes over A. A tilting complex T is a finitely generated complex of finitely generated projective modules, which does not admit selfextensions and which has the property that the smallest triangulated subcategory of D(A) which contains T also contains all...
متن کاملTilting Theory for Coherent Rings and Almost Hereditary Noetherian Rings
We generalize two major ways of obtaining derived equivalences, the tilting process by Happel, Reiten and Smalø and Happel’s Tilting Theorem, to the setting of finitely presented modules over right coherent rings. Moreover, we extend the characterization of quasi–tilted artin algebras as the almost hereditary ones to all right noetherian rings. We also give a streamlined and general presentatio...
متن کاملA pairing in homology and the category of linear tilting complexes for a quasi-hereditary algebra
We show that there exists a natural non-degenerate pairing of the homomorphism space between two neighbor standard modules over a quasi-hereditary algebra with the first extension space between the corresponding costandard modules and vise versa. Investigation of this phenomenon leads to a family of pairings involving standard, costandard and tilting modules. In the graded case, under some ”Kos...
متن کاملBootstrap Tilting Conndence Intervals Bootstrap Tilting Conndence Intervals
Bootstrap tilting con dence intervals could be the method of choice in many applications for reasons of both speed and accuracy With the right implementation tilting intervals are times as fast as bootstrap BC a limits in terms of the number of bootstrap samples needed for comparable simulation accuracy Thus bootstrap samples might su ce instead of Tilting limits have other desirable properties...
