Ju l 1 99 6 Fuzzy Space - Time

نویسنده

  • J. Madore
چکیده

A review is made of recent efforts to define linear connections and their corresponding curvature within the context of noncommutative geometry. As an application it is suggested that it is possible to identify the gravitational field as a phenomenological manifestation of space-time commutation relations and to thereby clarify its role as an ultraviolet regularizer.

We argue that correct account of the quantum properties of macroscopic objects which form reference frames (RF) demand the change of the standard space-time picture accepted in Quantum Mechanics. Galilean or Lorentz space-time transformations are shown to become incorrect in this case and for the description of transformations between different RF the special quantum space-time transformations ...

Shown are that the current notion of cosmological expansion is contradicted by the equivalence principle, and that the correct theory involves a fundamental principle of physical scale predicting the cosmological constant, planetary Hubble flow and all aspects of the deep space anomaly.

We introduce an associative algebra BR, whose exchange properties are inferred from the scattering processes in integrable models with reflecting boundary conditions in 1+1 space-time dimensions. We investigate the basic properties of BR and some natural generalizations of it. The Fock representations associated with certain involutions in BR are also derived. As an application of these results...

Admissibility analysis for discrete-time singular systems with time-varying delays by adopting the state-space Takagi-Sugeno fuzzy model

This paper is pertained with the problem of admissibility analysis of uncertain discrete-time nonlinear singular systems by adopting the state-space Takagi-Sugeno fuzzy model with time-delays and norm-bounded parameter uncertainties. Lyapunov Krasovskii functionals are constructed to obtain delay-dependent stability condition in terms of linear matrix inequalities, which is dependent on the low...

We construct higher-spin N=1 super algebras as extensions of the super Virasoro algebra containing generators for all spins s ≥ 3/2. We find two distinct classical (Poisson) algebras on the phase super space. Our results indicate that only one of them can be consistently quantized.
