Let 𝒫2(ℝd) be the space of probability measures on ℝd with finite second moment. The path independence of additive functionals of McKean–Vlasov SDEs is characterized by PDEs on the product space ℝd×𝒫2(ℝd) equipped with the usual derivative in space variable and Lions’ derivative in distribution. These PDEs are solved by using probabilistic arguments developed from Ref. 2. As a consequence, the path

Interacting Fock spaces and subproduct systems Infin. Dimens. Anal. Quantum Probab. Relat. Top. (IF 0.556) Pub Date : 2020-12-29 Malte Gerhold; Michael Skeide
We present a new more flexible definition of interacting Fock space that allows to resolve in full generality the problem of embeddability. We show that the same is not possible for regularity. We apply embeddability to classify interacting Fock spaces by squeezings. We give necessary and sufficient criteria for when an interacting Fock space has only bounded creators, giving thus rise to new classes

Quantum Strassen’s theorem Infin. Dimens. Anal. Quantum Probab. Relat. Top. (IF 0.556) Pub Date : 2020-12-29 Shmuel Friedland; Jingtong Ge; Lihong Zhi
Strassen’s theorem circa 1965 gives necessary and sufficient conditions on the existence of a probability measure on two product spaces with given support and two marginals. In the case where each product space is finite, Strassen’s theorem is reduced to a linear programming problem which can be solved using flow theory. A density matrix of bipartite quantum system is a quantum analog of a probability

A variational interpretation for this limit is given, which shows that typically the quantities of interests tend to minimize a certain entropy. A quasi-compact operator argument is involved

We introduce an infinite-dimensional p-adic affine group and construct its irreducible unitary representation. Our approach follows the one used by Vershik, Gelfand and Graev for the diffeomorphism group, but with modifications made necessary by the fact that the group does not act on the phase space. However, it is possible to define its action on some classes of functions.

We prove that every stationary state in the annihilator of all Kraus operators of a weak coupling limit-type Markov generator consists of two pieces, one of them supported on the interaction-free subspace and the second one on its orthogonal complement. In particular, we apply the previous result to describe in detail the structure of a slightly modified quantum transport model due to Arefeva et al

Paschke’s version of Stinespring’s theorem associates a Hilbert C∗-module along with a generating vector to every completely positive map. Building on this, to every quantum dynamical semigroup (QDS) on a C∗-algebra 𝒜 one may associate an inclusion system E=(Et) of Hilbert 𝒜-𝒜-modules with a generating unit ξ=(ξt). Suppose ℬ is a von Neumann algebra, consider M2(ℬ), the von Neumann algebra of 2×2

We reduce the conditionally monotone (c-monotone) independence of Hasebe to tensor independence on suitably constructed larger algebras. For that purpose, we use the approach developed for a reduction of similar type for boolean, free and monotone independences.

We introduce the quadratic analog of the tensor Bogolyubov representation of the CCR.

Stochastic Navier–Stokes equations perturbed by Lévy noise with hereditary viscosity Infin. Dimens. Anal. Quantum Probab. Relat. Top. (IF 0.556) Pub Date : 2019-04-24 Manil T. Mohan; Sivaguru S. Sritharan
In this paper, we study the stochastic Navier–Stokes equations (SNSE) perturbed by Lévy noise in three dimensions with a hereditary viscous term which depends on the past history. We establish the local solvability of the Cauchy problem for such systems. The local monotonicity property of the nonlinear term of the cutoff problem and a stochastic generalization of the Minty–Browder technique are exploited

Classification of globally colorized categories of partitions Infin. Dimens. Anal. Quantum Probab. Relat. Top. (IF 0.556) Pub Date : 2019-01-09 Daniel Gromada
Set partitions closed under certain operations form a tensor category. They give rise to certain subgroups of the free orthogonal quantum group On+, the so-called easy quantum groups, introduced by Banica and Speicher in 2009. This correspondence was generalized to two-colored set partitions, which, in addition, assign a black or white color to each point of a set. Globally colorized categories of

Pascal white noise harmonic analysis on configuration spaces and applications Infin. Dimens. Anal. Quantum Probab. Relat. Top. (IF 0.556) Pub Date : 2019-01-09 Anis Riahi; Habib Rebei
In this paper, we unify techniques of Pascal white noise analysis and harmonic analysis on configuration spaces establishing relations between the main structures of both ones. Fix a Random measure σ on a Riemannian manifold X, we construct on the space of finite compound configuration space Ω0 the so-called Lebesgue–Pascal measure λσ̂ and as a consequence we obtain the Pascal measure μσ̂ on the compound
