Wireless Sensor Networks (WSN) consist of distributed sensors enabling monitoring of physical or environmental conditions like temperature, pressure, humidity, accelerations etc. When a sensor node includes a micro-controller, the acquired data can a

In the book of Haag [Local Quantum Physics (Springer Verlag, Berlin, 1992)] about local quantum field theory the main results are obtained by the older methods of C * - and W * -algebra theory. A great advance, especially in the theory of W * -algebr

For a von Neumann algebra with a cyclic and separating vector it will be shown that the von Neumann subalgebras with the same cyclic vector can uniquely be characterized by one-parametric operator-valued functions obeying a set of conditions. Since t

In this paper we investigate the conditions under which the ordered spaces defined in [1] are locally diffeomorphic to ℝ N . In Sect.~1 we give an introduction and an overview of the results. In Sect. 2 we show that the axioms of [1] do not suffice

Let M be a von Neumann algebra acting on a Hilbert space H and Ω∞ H a cyclic and separating vector for M. If there exists a half-sided translation for M, i.e. a continuous unitary group U(t) with U(t)Ω=Ω, a non-negative spectrum fulfilling Ad U(

It will be shown that, in a theory of local observables, the modular group of the algebra of any wedge domain acts as local iff the theory is Poincare covariant, fulfils wedge duality and, moreover, the observables fulfil some reality condition with

Given a von Neumann algebra M with cyclic and separating vector Ω and with the modular group δit which is associated with the pair (M, Ω) we will investigate the von Neumann subalgebras N ⊂ M which fulfil the principle of half-sided modular incl

In this note we will give a construction of the Poincare group out of the modular groups of the wedge algebras provided the groups act on the algebra of every double cone like the associated Lorentz boosts. This construction will use the concept of h

This Letter deals with the theory of local observables in the vacuum sector. We will give necessary and sufficient conditions which imply that the wedge duality is a consequence of the Lorentz covariance of this theory.
