On the notion(s) of duality for Markov processes

  title={On the notion(s) of duality for Markov processes},
  author={Sabine Jansen and Noemi Kurt},
  journal={Probability Surveys},
We provide a systematic study of the notion of duality of Markov processes with respect to a function. We discuss the relation of this notion with duality with respect to a measure as studied in Markov process theory and potential theory and give functional analytic results including existence and uniqueness criteria and a comparison of the spectra of dual semi-groups. The analytic framework builds on the notion of dual pairs, convex geometry, and Hilbert spaces. In addition, we formalize the…

Stochastic Duality and Orthogonal Polynomials

For a series of Markov processes we prove stochastic duality relations with duality functions given by orthogonal polynomials. This means that expectations with respect to the original process (which

Orthogonal Dualities of Markov Processes and Unitary Symmetries

We study self-duality for interacting particle systems, where the particles move as continuous time random walkers having either exclusion interaction or inclusion interaction. We show that

The Algebraic Approach to Duality: An Introduction

This survey article gives an elementary introduction to the algebraic approach to Markov process duality, as opposed to the pathwise approach. In the algebraic approach, a Markov generator is written

Orthogonal Stochastic Duality Functions from Lie Algebra Representations

Stochastic duality functions for specific Markov processes are obtained using representation theory of Lie algebras using representations of the Heisenberg algebra andsu(1,1) for orthogonal (self-)duality functions in terms of hypergeometric functions for Specific interacting particle processes and interacting diffusion processes.

Pathwise Duals of Monotone and Additive Markov Processes

This paper develops a systematic treatment of monotonicity-based pathwise dualities for Markov processes taking values in partially ordered sets. We show that every Markov process that takes values

Duality for Stochastic Models of Transport

We study three classes of continuous time Markov processes (inclusion process, exclusion process, independent walkers) and a family of interacting diffusions (Brownian energy process). For each model

Stein's method and duality of Markov processes

One of the key ingredients to successfully apply Stein's method for distributional approximation are solutions to the Stein equations and their derivatives. Using Barbour's generator approach, one

Duality for a class of continuous-time reversible Markov models

Using a conditional probability structure, this work identifies the dual of some non-conjugate models, namely the queue model and a simple birth, death and immigration process, to ensure that the computation of the predictor operators can be done via finite sums.

Analysis of non-reversible Markov chains via similarity orbits

An in-depth analysis of non-reversible Markov chains on denumerable state space from a similarity orbit perspective is developed, and a particular similarity orbit of reversible Markov kernels is investigated, which is called the pure birth orbit.

Discrete self-similar and ergodic Markov chains

The first aim of this paper is to introduce a class of Markov chains on Z+ which are discrete self-similar in the sense that their semigroups satisfy an invariance property expressed in terms of a



Duality and Hidden Symmetries in Interacting Particle Systems

In the context of Markov processes, both in discrete and continuous setting, we show a general relation between duality functions and symmetries of the generator. If the generator can be written in

Quantum operators in classical probability theory. IV. Quasi-duality and thinnings of interacting particle systems

Duality has proved to be a powerful technique in the study of interacting particle systems (IPS). This concept can be enlarged and a quasi-duality defined between various pairs of IPS previously

Duality and intertwining for discrete Markov kernels: relations and examples

We supply some relations that establish intertwining from duality and give a probabilistic interpretation. This is carried out in the context of discrete Markov chains, fixing up the background of

Quantum Operators in Classical Probability Theory: II. The Concept of Duality in Interacting Particle Systems

Duality has proved to be a powerful tool in the theory of interacting particle systems. The approach in this paper is algebraic rather than via Harris diagrams. A form of duality is found which

Strong stationary duality for continuous-time Markov chains. Part I: Theory

LetX(t), 0≤t<∞, be an ergodic continuous-time Markov chain with finite or countably infinite state space. We construct astrong stationary dual chainX* whose first hitting times yield bounds on the

Pathwise construction of certain moment dualities and application to population models with balancing selection

We investigate dual mechanisms for interacting particle systems. Generalizing an approach of Alkemper and Hutzenthaler in the case of coalescing duals, we show that a simple linear transformation


We derive a unified stochastic picture for the duality of a resampling-selection model with a branching-coalescing particle process (cf. [1]) and for the self-duality of Feller’s branching diffusion

The classification of birth and death processes

In the applications one is given the matrix A and it is required to construct P(t) and to study the properties of the corresponding stochastic process. The existence, uniqueness, and the analytic

The purpose of this paper is to present a probabilistic proof of the well-known result stating that the time needed by a continuous-time finite birth and death process for going from the left end to

Diffusions, Markov processes, and martingales

This celebrated book has been prepared with readers' needs in mind, remaining a systematic treatment of the subject whilst retaining its vitality. The second volume follows on from the first,
