Smith–Treumann theory and the linkage principle

چکیده
Abstract We apply Treumann’s “Smith theory for sheaves” in the context of Iwahori–Whittaker model Satake category. deduce two results representation reductive algebraic groups over fields positive characteristic: (a) a geometric proof linkage principle; (b) character formula tilting modules terms $\ell $ ℓ -canonical basis, valid all blocks and characteristics.

از محوری ترین اثراتی که یک فیلم سینمایی ایجاد می کند دیالوگ هایی است که هنرپیش گان فیلم میگویند. به زعم یک فیلم ساز, یک شیوه متأثر نمودن مخاطب از اثر منظوره نیروی گفتارهای گوینده, مثل نیروی عاطفی, ترس آور, غم انگیز, هیجان انگیز و غیره, است. این مطالعه به بررسی این مسأله مبادرت کرده است که آیا نیروی فراگفتاری هنرپیش گان به مثابه ی اعمال گفتاری در پنج فیلم هالیوودی در نسخه های دوبله شده باز تولید...
15 صفحه اولBayesian Confirmation Theory and The Likelihood Principle
The likelihood principle (LP) is a core issue in disagreements between Bayesian and frequentist statistical theories. Yet statements of the LP are often ambiguous, while arguments for why a Bayesian must accept it rely upon unexamined implicit premises. I distinguish two propositions associated with the LP, which I label LP1 and LP2. I maintain that there is a compelling Bayesian argument for L...
متن کاملThe Lefschetz Principle , Fixed Point Theory , and Index Theory
This is a rough historical account of some uses of the Lefschetz Principle in fixed point theory and index theory. The Lefschetz Principle states that the alternating sum of the traces on cohomology (a global and rigid invariant) is equal to the alternating sum of the traces on the underlying cochain complex (a local and far less rigid invariant). The original Lefschetz Theorem for compact poly...

متن کاملLinkage principle, Multi-dimensional Signals and Blind Auctions
We compare the seller’s expected revenue in a second price sealed bid auction for a single object in which bidders receive multidimensional signals. Bidders’ valuations for the object depend on their signals and a signal observed privately by the seller. We show in various examples that the seller can be better off not revealing publicly his signal. Hence the linkage principle does not necessar...
