We study a particular class of rationally connected manifolds, X ⊂ P , such that two general points x, x′ ∈ X may be joined by a conic contained in X. We prove that these manifolds are Fano, with b2 6 2. Moreover, a precise classification is obtained for b2 = 2. Complete intersections of high dimension with respect to their multi-degree provide examples for the case b2 = 1. The proof of the cla...
متن کاملA Poisson Relation for Conic Manifolds
Let X be a compact Riemannian manifold with conic singularities, i.e. a Riemannian manifold whose metric has a conic degeneracy at the boundary. Let ∆ be the Friedrichs extension of the Laplace-Beltrami operator on X. There are two natural ways to define geodesics passing through the boundary: as “diffractive” geodesics which may emanate from ∂X in any direction, or as “geometric” geodesics whi...
متن کاملInstantons on Conic 4-manifolds: Fredholm Theory
We study the self-duality operator on conic 4-manifolds. The self-duality operator can be identified as a regular singular operator in the sense of Brüning and Seeley, based on which we construct its parametrizations and closed extensions. We also compute the indexes.

متن کامل5-manifolds: 1-connected*
We recall the classification of closed smooth simply-connected 5manifolds begun by Smale in 1962 and completed by Barden in 1965. We also give a construction of every such manifold which differs from Barden’s original construction.
