Hypermultiplets, Hyperkähler Cones and Quaternion-Kähler Geometry
We study hyperkähler cones and their corresponding quaternion-Kähler spaces. We present a classification of 4(n − 1)-dimensional quaternionKähler spaces with n abelian quaternionic isometries, based on dualizing superconformal tensor multiplets. These manifolds characterize the geometry of the hypermultiplet sector of perturbative moduli spaces of type-II strings compactified on a Calabi-Yau ma...
متن کاملTensor supermultiplets and toric quaternion - Kähler geometry †
We review the relation between 4n-dimensional quaternion-Kähler metrics with n + 1 abelian isometries and superconformal theories of n + 1 tensor supermultiplets. As an application we construct the class of eight-dimensional quaternion-Kähler metrics with three abelian isometries in terms of a single function obeying a set of linear second-order partial differential equations. Talk given by F.S...
متن کاملAffine circle geometry over quaternion skew fields
We investigate the affine circle geometry arising from a quaternion skew field and one of its maximal commutative subfields.
متن کاملQuaternion Higgs and the Electroweak Gauge Group
We show that, in quaternion quantum mechanics with a complex geometry, the minimal four Higgs of the unbroken electroweak theory naturally determine the quaternion invariance group which corresponds to the Glashow group. Consequently, we are able to identify the physical significance of the anomalous Higgs scalar solutions. We introduce and discuss the complex projection of the Lagrangian density.
متن کاملspherical interpretation of plane geometry in menelaus of alexandria’s sphaerica
menelaus’ sphaerica can be considered as the most important classical text in the tradition of spherics books, written with the aim of the solution of problems arising in spherical astonomy. euclid’s elements is the the most important book on plane geometry. this article aims at a comparative study of menelaus’s sphaerica and euclid’s elements, to show that book i of sphaerica is an attempt to ...
