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 orthogonal self-dualities arise from unitary symmetries of the Markov generator. For these symmetries we provide two equivalent expressions that are related by the Baker-Campbell-Hausdorff formula. The first expression is the exponential of an anti Hermitian operator and thus is unitary by inspection; the…

Orthogonal Stochastic Duality Functions from Lie Algebra Representations
TLDR
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.

TLDR
A systematic orthogonal decomposition of the fluctuation fields of local functions, where the order of every term can be quantified, implies a quantitative generalization of the Boltzmann–Gibbs principle.

Factorized Duality, Stationary Product Measures and Generating Functions
TLDR
The approach is based on a general relation between factorized duality functions and stationary product measures and an intertwining relation provided by generating functions, which discloses all simple factorized self-duality functions for interacting diffusion systems such as the Brownian energy process.
