چکیده
Let M be a four-dimensional orientable manifold equipped with a Minkowski type metric g and with a polarization. In general relativity such a manifoldM is used as a stage for all physical phenomena. When describing the spin phenomenon M is additionally assumed to be a spin manifold. In this case it admits two spinor bundles: the bundle of Weyl spinors SM and the bundle of Dirac spinors DM (see definitions below). Relativistic quantum particles inM are described by their fields, while fields are introduced through their contribution to the action

Spinors, Jets, and the Einstein Equations
Many important features of a eld theory, e.g., conserved currents, symplectic structures, energy-momentumtensors, etc., arise as tensors locally constructed from the elds and their derivatives. Such tensors are naturally de ned as geometric objects on the jet space of solutions to the eld equations. Modern results from the calculus on jet bundles can be combined with a powerful spinor parametri...

are closed. Manifolds carrying a hypersymplectic structure have a rich geometry, the neutral metric is Kähler and Ricci flat and its holonomy group is contained in Sp(2n,R) ([8]). Moreover, the Levi Civita connection is flat, when restricted to the leaves of the canonical foliations associated to the product structure given by E (see [2]). Metrics associated to a hypersymplectic structure are a...
متن کاملCusped hyperbolic 3-manifolds: canonically CAT(0) with CAT(0) spines
We prove that every finite-volume hyperbolic 3-manifold M with p ≥ 1 cusps admits a canonical, complete, piecewise Euclidean CAT(0) metric, with a canonical projection to a CAT(0) spine K∗ M . Moreover: (a) The universal cover of M endowed with the CAT(0) metric is a union of Euclidean half-spaces, glued together by identifying Euclidean polygons in their bounding planes by pairwise isometry; (...
متن کاملPerturbations of the metric in Seiberg-Witten equations
Let M a compact connected orientable 4-manifold. We study the space Ξ of Spin-structures of fixed fundamental class, as an infinite dimensional principal bundle on the manifold of riemannian metrics on M . In order to study perturbations of the metric in Seiberg-Witten equations, we study the transversality of universal equations, parametrized with all Spin-structures Ξ. We prove that, on a com...
متن کاملSupersymmetric Black Holes
The effective action of N = 2, d = 4 supergravity is shown to acquire no quantum corrections in background metrics admitting super-covariantly constant spinors. In particular, these metrics include the Robinson-Bertotti metric (product of two 2dimensional spaces of constant curvature) with all 8 supersymmetries unbroken. Another example is a set of arbitrary number of extreme Reissner-Nordström...
