Sesquilinear quantum stochastic analysis in Banach space [PDF]

open access: yes, 2014
A theory of quantum stochastic processes in Banach space is initiated. The processes considered here consist of Banach space valued sesquilinear maps.

E-semigroups Subordinate to CCR Flows [PDF]

open access: yes, 2010
The subordinate E-semigroups of a fixed E-semigroup are in one-to-one correspondence with local projection-valued cocycles of that semigroup. For the CCR flow we characterise these cocycles in terms of their stochastic generators, that is, in terms of ...

Simply Generated Trees, B-series and Wigner Processes [PDF]

open access: yes, 2004
We consider simply generated trees and study multiplicative functions on rooted plane trees. We show that the associated generating functions satisfy differential equations or difference equations.

Monotone independence, comb graphs and Bose-Einstein condensation [PDF]

open access: yes, 2004
The adjacency matrix of a comb graph is decomposed into a sum of monotone independent random variables with respect to the vacuum state. The vacuum spectral distribution is shown to be asymptotically the arcsine law as a consequence of the monotone ...

Approximation of quantum Levy processes by quantum random walks [PDF]

open access: yes, 2007
Every quantum Levy process with a bounded stochastic generator is shown to arise as a strong limit of a family of suitably scaled quantum random walks.Comment: 7 ...

Analysis of unbounded operators and random motion

open access: yes, 2009
We study infinite weighted graphs with view to \textquotedblleft limits at infinity,\textquotedblright or boundaries at infinity. Examples of such weighted graphs arise in infinite (in practice, that means \textquotedblleft very\textquotedblright large ...

The Quantum Black-Scholes Equation [PDF]

open access: yes, 2006
Motivated by the work of Segal and Segal on the Black-Scholes pricing formula in the quantum context, we study a quantum extension of the Black-Scholes equation within the context of Hudson-Parthasarathy quantum stochastic calculus.

Quantum Feynman-Kac perturbations

open access: yes, 2013
We develop fully noncommutative Feynman-Kac formulae by employing quantum stochastic processes. To this end we establish some theory for perturbing quantum stochastic flows on von Neumann algebras by multiplier cocycles.

Classical dilations \`a la Hudson-Parthasarathy of Markov semigroups

open access: yes, 2007
We study the Classical Probability analogue of the dilations of a quantum dynamical semigroup defined in Quantum Probability via quantum stochastic differential equations.

Unbounded operators, Lie algebras, and local representations

open access: yes, 2014
We prove a number of results on integrability and extendability of Lie algebras of unbounded skew-symmetric operators with common dense domain in Hilbert space.
