We present SPACE an application-level protocol for secure automatic ad-hoc connection-establishment between two devices based on their address book entries. Our protocol is based on the simple premise that if two people have each others contact details in their address books, they probably know and trust each other in some limited way and this can form a basis for a trust relationship between t...

We aim to combine the semantics of spatial natural language specified as a linguistically motivated ontology, the Generalized Upper Model, with spatial logics or ontologies that specify space according to certain conceptualisations, based on regions, shapes, orientations, distances, or object properties. Such combinations, however, introduce uncertainties of various kinds, caused by different l...

The Space Physics Archive Search and Extract (SPASE) project is an international collaboration among Heliophysics (solar and space physics) groups concerned with data acquisition and archiving. The SPASE group has simplified the search for data through the development of the SPASE Data Model as a common method to describe data sets in the archives. The data model is an XML-based schema and is n...

In this paper we study two different topics. The first topic is the applications of the geometric quantization scheme of Witten introduced in [2] and [15] to the problem of the quantum background independence in string theory. The second topic is the introduction of a Z structure on the tangent space of the moduli space of polarized CY threefolds M(M). Based on the existence of a Z structure on...

We prove that the natural hyper-KK ahler metrics on the moduli space of charge k instantons over Euclidean four-space and on the space of ADHM matrices coincide. We use this to deduce formulae relating expressions in the curvature of a connection to invariant polynomials in the ADHM matrices corresponding to this connection. These arise from consideration of the group of symmetries acting on th...

The Fedosov deformation quantization on a cotangent bundle with a symplectic connection induced by some Riemannian connection on a base space is considered. Construction of the symplectic connection on the cotangent determined by the Riemannian connection is proposed. A detailed analysis of an Abelian connection and flat sections representing special classes of functions is presented. Some phys...

We study the Gauss-Manin connection for the moduli space of an arrangement of complex hyperplanes in the cohomology of a complex rank one local system. We define formal Gauss-Manin connection matrices in the Aomoto complex and prove that, for all arrangements and all local systems, these formal connection matrices specialize to Gauss-Manin connection matrices.
