We deal here with the notion of statistical order and apply it to a system interacting fermions endowed an SU2 × symmetry. The discussion takes place in thermal quantum scenario. Two distinct fermion–fermion interactions are at play. One them is well-known spin–flip interaction. other pairing interaction responsible for nuclear superconductivity. used novel quantifiers that yield insights regar...

Deformation spaces Hom(π,G)/G of representations of the fundamental group π of a surface Σ in a Lie group G admit natural actions of the mapping class group ModΣ, preserving a Poisson structure. When G is compact, the actions are ergodic. In contrast if G is noncompact semisimple, the associated deformation space contains open subsets containing the Fricke-Teichmüller space upon which ModΣ acts...

Appropriate awareness support has been an issue in the area of Computer-Supported Cooperative Work (CSCW) for quite a while. Yet, many challenges like the dual trade-off between awareness and privacy and awareness and disruption still remain. In this paper we present our human-centred approach on how to utilise group dynamics and team development specific information patterns to control awarene...

Event-Based Social Networks (EBSNs) such as Meetup, Plancast, etc., have become popular platforms for users to plan and organize social events with friends and acquaintances. These EBSNs provide rich online and offline user interactions, and rich event content information which can be leveraged for personalized group-event recommendations. In this paper, we propose collaborative-filtering based...

Classical dynamics concepts are analysed in the basic mathematical setting of state transition systems where time and space are both completely discrete and no structure is assumed on the state’s space. Interesting relationships between attractors and recurrence are identified and some features of chaos are expressed in simple, set theoretic terms. String dynamics is proposed as a unifying conc...

We investigate the geometrical features of one-dimensional wave propagation, whose dynamics is described by the (2+1)-dimensional Lorentz group. We find many interesting geometrical ingredients such as spinorlike behavior of wave amplitudes, gauge transformations, Bloch-type equations, and Lorentz-group Berry phases. We also propose an optical experiment to verify these effects. PACS numbers: 0...

This paper presents a comparative analysis of two resource reservation protocols, ST-II [6] and RSVP [7], in support of an Integrated Services Packet Network (ISPN). We use simulations to examine the network-wide resource requirements for each protocol to support a number of application communication styles, across a range of group sizes and membership distributions. We also present a compariso...
