The sectional category of spherical fibrations
We give homological conditions which determine sectional category, secat, for rational spherical fibrations. In the odd dimensional case the secat is the least power of the Euler class which is trivial. In the even dimensional case secat is one when a certain homology class in twice the dimension of the sphere is −1 times a square. Otherwise secat is two. We apply our results to construct a fib...
متن کاملFibrations in ∞-category Theory
In this short expository note, we discuss, with plenty of examples, the bestiary of fibrations in quasicategory theory. We underscore the simplicity and clarity of the constructions these fibrations make available to end-users of higher category theory.
متن کاملA Note on Del Pezzo Fibrations of Degree 1
Let O be a discrete valuation ring with residue field k of characteristic 0. We denote by K the quotient field of O. A model of a variety XK defined over K is a flat scheme X defined over Spec O whose generic fiber is isomorphic to XK . Fano fibrations are models of smooth Fano varieties defined over K. In particular, del Pezzo fibrations of degree d are models of smooth del Pezzo surfaces of d...
متن کاملA field theory for symplectic fibrations over surfaces
We introduce in this paper a field theory on symplectic manifolds that are fibered over a real surface with interior marked points and cylindrical ends. We assign to each such object a morphism between certain tensor products of quantum and Floer homologies that are canonically attached to the fibration. We prove a composition theorem in the spirit of QFT, and show that this field theory applie...
متن کاملQuantum Curves for Hitchin Fibrations and the Eynard–Orantin Theory
We generalize the topological recursion of Eynard–Orantin (JHEP 0612:053, 2006; Commun Number Theory Phys 1:347–452, 2007) to the family of spectral curves of Hitchin fibrations. A spectral curve in the topological recursion, which is defined to be a complex plane curve, is replaced with a generic curve in the cotangent bundle T ∗C of an arbitrary smooth base curve C . We then prove that these ...
