EXPONENT MATRICES AND TILED ORDERS OVER DISCRETE VALUATION RINGS

    https://doi.org/10.1142/S0218196705002724Cited by:4 (Source: Crossref)

    Exponent matrices appear in the theory of tiled orders over a discrete valuation ring. Many properties of such an order and its quiver are fully determined by its exponent matrix. We prove that an arbitrary strongly connected simply laced quiver with a loop in every vertex is realized as the quiver of a reduced exponent matrix. The relations between exponent matrices and finite posets, Markov chains, and doubly stochastic matrices are discussed.
