Abstract
We present a synthesis of a number of developments which have been made around the celebrated Tsirelson's equation (1975), conveniently modified in the framework of a Markov chain taking values in a compact group \(G\), and indexed by negative time. To illustrate, we discuss in detail the case of the one-dimensional torus \(G=\mathbb{T}\).

AMS 2000 subject classifications: Primary 60J05; secondary 60B15, 60J50, 37H10.

Keywords: Tsirelson's equation, evolution process, extremal points, strong solution, uniqueness in law.
