Wick Calculus for Noncommutative White Noise Corresponding to q-Deformed Commutation Relations [PDF]
We derive the Wick calculus for test and generalized functionals of noncommutative white noise corresponding to q-deformed commutation relations with $q\in(-1,1)$.We construct a Gel'fand triple centered at the q-deformed Fock space in which both the ...

A connection between the Poissonian Wick product and the discrete convolution
Inspired by Lemma 3.1 in (4), where a connection between the Gaussian Wick product and the classic convolution product is shown, we prove that the Wick product associated to the Poisson distribution is re- lated to the discrete convolution and hence to the law of the sum of discrete independent random variables. The proof of the main result is based on

On the Wick product and Wong-Zakai approximations. [PDF]
This thesis is a compilation of 6 papers that the author has written together with Alberto Lanconelli (chapters 3, 5 and 8) and Hyun-Jung Kim (ch 7). The logic thread that link all these chapters together is the interest to analyze and approximate the solutions of certain stochastic differential equations using the so called Wick product as the basic ...

The wick-malliavin approximation of elliptic problems with log-normal random coefficients
In this work, we discuss the approximation of elliptic problems with log-normal random coefficients using the Wick product and the Mikulevicius-Rozovskii formula.

Hopf-algebraic Deformations of Products and Wick Polynomials [PDF]
Abstract We present an approach to cumulant–moment relations and Wick polynomials based on extensive use of convolution products of linear functionals on a coalgebra. This allows, in particular, to understand the construction of Wick polynomials as the result of a Hopf algebra deformation under the action of linear automorphisms induced ...

Wick products of the free Bose field
AbstractWe consider Wick products of the free Bose field in the abstract context of a complex Hilbert space H equipped with a self-adjoint operator A satisfying A ⩾ εI for some ε > 0. Let (K, W, Γ, ν) be the free Bose field over H, and let H = dΓ(A). Let H∞ and K∞ denote D∞(A) and D∞(H) respectively, given their natural Frechét topologies. Then for any

Wick’s Theorem for Matrix Product States [PDF]
Matrix-product states and their continuous analogues are variational classes of states that capture quantum many-body systems or quantum fields with low entanglement; they are at the basis of the density-matrix renormalization group method and continuous variants thereof.
