A shuffle algebra point of view on operator-valued probability theory

چکیده
We extend the shuffle algebra perspective on scalar-valued non-commutative probability theory to operator-valued case. Given an space with B acting it (on left and right), we associate operators in operad of multilinear maps distribution free cumulants a random variable. These define representation PRO non-crossing partitions. Using concepts from higher category theory, specifically 2-monoidal categories, notion unshuffle Hopf underlying PRO. introduce words insertions show that both latter partitions are algebras. The two relate by mean map bialgebra (in sense) which call splitting map. Ultimately, obtain half-shuffle fixed point equation corresponding moment-cumulant relations bicollection homomorphisms insertions. Right laws interpreted framework boolean monotone respectively.

A Boolean-valued probability theory
New foundations for probability theory are suggested and investigated, derived from the formalized systems theory and using also some other branches of mathematical logic. The probability measures are supposed to take their values not in the unit interval of reals, but in a special kind of Boolean algebras. Some analogies as well as differences of this approach with respect to the classical Kol...
متن کاملOperator-valued tensors on manifolds
In this paper we try to extend geometric concepts in the context of operator valued tensors. To this end, we aim to replace the field of scalars $ mathbb{R} $ by self-adjoint elements of a commutative $ C^star $-algebra, and reach an appropriate generalization of geometrical concepts on manifolds. First, we put forward the concept of operator-valued tensors and extend semi-Riemannian...
متن کاملAlgebra and Probability in Many-Valued Reasoning
Many-valued reasoning is a well-established domain of investigation with thriving connections to several areas of logic, mathematics, philosophy, and computer science. In May 2009, an international workshop on Algebra and Probability in Many-Valued Logics was held in Darmstadt, Germany. Established as well as younger researchers in the field gathered together to foster progress on various aspec...
متن کاملOperator Probability Theory
This article presents an overview of some topics in operator probability theory. We do not strive for generality and only simple methods are employed. To give the reader a flavor of the subject we concentrate on the two most important topics, the law of large numbers and the central limit theorem.
متن کاملPDE from a probability point of view
These notes are for a course I gave while on sabbatical at UBC. It presupposes the reader is familiar with stochastic calculus; see the notes on my web page for Stochastic Calculus, for example. These notes for the most part are based on my book Diffusions and Elliptic Operators, Springer-Verlag, 1997. The topics covered are: stochastic differential equations, solving PDEs using probability, Ha...
