Hidden Symmetries of Stochastic Models
In the matrix product states approach to n species diffusion processes the stationary probability distribution is expressed as a matrix product state with respect to a quadratic algebra determined by the dynamics of the process. The quadratic algebra defines a noncommutative space with a SUq(n) quantum group action as its symmetry. Boundary processes amount to the appearance of parameter depend...

متن کاملLooking beyond the Thermal Horizon: Hidden Symmetries in Chiral Models
In thermal states of chiral theories, as recently investigated by H.-J. Borchers and J. Yngvason, there exists a rich group of hidden symmetries. Here we show that this leads to a radical converse of of the Hawking-Unruh observation in the following sense. The algebraic commutant of the algebra associated with a (heat bath) thermal chiral system can be used to reprocess the thermal system into ...
متن کاملTopics in Hidden Symmetries
This note being devoted to some aspects of the inverse problem of representation theory contains a new insight into it illustrated by two topics. The attention is concentrated on the manner of representation of abstract objects by the concrete ones as well as on the abstract objects themselves. This paper being a continuation of the previous three parts [1] explicates novel features of the gene...
متن کاملIn Hidden Symmetries . Ii
This short paper being devoted to some aspects of the inverse problem of the representation theory briefly treats the interrelations between the author’s approach to the setting free of hidden symmetries and the researches of D.P.Zhelobenko in the generalized Mickelsson algebras and related topics. This short paper being a continuation of the first part [1] is a collection of examples illustrat...
