Algebraic random walks in the setting of symmetric functionsAlgebraic random walks in the setting of symmetric functions Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2018-05-112017enUsing the standard formulation of algebraic random walks (ARWs) via coalgebras, we consider ARWs for co- and Hopf-algebraic structures in the ring of symmetric functions. These derive from different types of products by dualisation, giving the dual pairs of outer multiplication and outer coproduct, inner multiplication and inner coproduct, and symmetric function plethysm and plethystic coproduct. Adopting standard coordinates for a class of measures (and corresponding distribution functions) to guarantee positivity and correct normalisation, we show the effect of appropriate walker steps of the outer, inner and plethystic ARWs. If the coordinates are interpreted as heights or occupancies of walker(s) at different locations, these walks introduce translations, dilations (scalings) and inflations of the height coordinates, respectively. http://creativecommons.org/licenses/by/4.0/Reports on Mathematical Physics793347-366 Jarvis, Peter, 1937- Ellinas Dimosthenis Ελληνας Δημοσθενης Elsevier Algebraic combinatorics Hopf algebras Plethysm Random walks
