    Coronoids - an application for Madras's Pattern Theorem

    22 janvier 2003 - 10:00Salle de séminaires IRMA

    Coronoids are connected clusters on the hexagonal lattice whose holes have at least size two. Hence the model falls between polygons and polyominoes on the hexagonal lattice. I will analyse how the size and number of holes influences the growth constant and the critical exponent in the different models. Madras' Pattern Theorem is an essential tool for this.

    Hexagonal Animals

    21 mai 2003 - 10:00Salle de séminaires IRMA

    A hexagonal animal (also called: hexagonal system, benzenoid system, hexagonal polyomino) is a geometric figure obtained by arranging congruent regular hexagons in the plane, so that two hexagons are either disjoint or have a common edge. The lecture presents the basic, mainly combinatorial, properties of hexagonal animals. Unsolved problems are pointed out. References: The lecturer published over 100 papers and several books on hexagonal systems and their applications.
