Riemann-roch for Algebraic Stacks:iii Virtual Structure Sheaves and Virtual Fundamental Classes
In this paper we apply the Riemann-Roch and Lefschetz-Riemann-Roch theorems proved in our earlier papers to define virtual fundamental classes for the moduli stacks of stable curves in great generality and establish various formulae for them.
متن کاملFibre Sequences and Localization of Simplicial Sheaves
In this paper, we provide criteria for fibre sequences of simplicial sheaves to be preserved by nullifications. This generalizes a result of Berrick and Dror Farjoun and allows a better understanding of unstable A-homotopy theory.
متن کاملVirtual Localization by Blind Persons
Localization performance and spatial hearing abilities of blind persons are complex issues. In everyday life we rely on the “fact” that blind people can hear better, without thinking of what “better” means. Localization performance depends on many parameters such as properties of the excitation signal, environmental conditions, individual aspects, and visual influence. Our goal was to create a ...
متن کاملLOCALLY PROJECTIVE MONOIDAL MODEL STRUCTURE FOR COMPLEXES OF QUASI-COHERENT SHEAVES ON P(k)
We will generalize the projective model structure in the category of unbounded complexes of modules over a commutative ring to the category of unbounded complexes of quasi-coherent sheaves over the projective line. Concretely we will define a locally projective model structure in the category of complexes of quasicoherent sheaves on the projective line. In this model structure the cofibrant obj...
متن کاملConstructible Sheaves on Simplicial Complexes and Koszul Duality
We obtain a linear algebra data presentation of the category Sh c (X,δ) of constructible with respect to perverse triangulation sheaves on a finite simplicial complex X. We also establish Koszul duality between Sh c (X, δ) and the category Mc(X, δ) of perverse sheaves constructible with respect to the triangulation
