We prove that the quiver of tiled order over a discrete valuation ring is strongly connected and simply laced. With such quiver we associate a finite ergodic Markov chain. We introduce the notion of the index \(in\,A\) of a right noetherian semiperfect ring \(A\) as the maximal real eigen-value of i...
