  • 24 December 2001
Abstract A class of C ∗ -algebras called quantum Heisenberg manifolds were introduced by Rieffel in (Comm. Math. Phys. 122 (1989) 531) as strict deformation quantization of Heisenberg manifolds.… Expand

Stochastic Integral Representation of Bounded Quantum Martingales in Fock Space
It is a classical theorem of Kunita and Watanabe [6] that every square integrable martingale adapted to the standard Brownian motion can be uniquely expressed as the stochastic integral of a… Expand

Quantum random walk revisited
In the framework of the symmetric Fock space over L 2 (R + ), the details of the approximation of the four fundamental quantum stochastic increments by the four appropriate spin-matrices are studied.… Expand

On pairs of projections in a Hilbert space
We give an algebraic derivation of the canonical form of a generic pair of projections. The result is used to determine the spectral shift of a pair of projections and various properties of Fredholm… Expand

Spectral shift function and trace formula
The complete proofs of Krein’s theorem on the spectral shift function and the trace formula are given for a pair of self-adjoint operators such that either (i) their difference is trace-class or (ii)… Expand

Quantum stop times
The notion of stop-time can be naturally translated in a quantum probabilistic framework and this problem has been studied by several authors [1], [2], [3], [4], [5]. Recently Parthasarathy and Sinha… Expand
