    Parsimonious reconstruction of sequence evolution and haplotype blocks: Finding the minimum number of recombination events by Song, Y, Hein, J

    Published 2003
    “…Our approach is deterministic and is based on the combinatorics of leaf-labelled rooted trees. In contrast to previously known approaches, which only yield estimated lower bounds, our approach always gives the exact minimum number of recombination events. …”

    Toric Hypersymplectic Quotients by Dancer, A, Swann, A

    Published 2004
    “…We give precise conditions for smoothness and non-degeneracy of such quotients and show how some properties of the quotient geometry and topology are constrained by the combinatorics of the cone configurations. Examples are studied, including non-trivial structures on R^{4n} and metrics on complements of hypersurfaces in compact manifolds.…”

    T-structures on some local Calabi-Yau varieties by Bridgeland, T

    Published 2005
    “…We use the theory of exceptional collections to describe t-structures on the derived category of coherent sheaves on ωZ. The combinatorics of these t-structures is determined by a natural action of an affine braid group, closely related to the well-known action of the Artin braid group on the set of exceptional collections on Z. © 2005 Elsevier Inc. …”

    Chromatic roots as algebraic integers by Adam Bohn

    Published 2012-01-01
    “…At a Newton Institute workshop on Combinatorics and Statistical Mechanics in 2008, two conjectures were proposed on the subject of which algebraic integers can be chromatic roots, known as the ``$α +n$ conjecture'' and the ``$nα$ conjecture''. …”

    Poset binomials and rainbow characters by Daniel Bragg, Nathaniel Thiem

    Published 2013-01-01
    “…These coefficients arise naturally in the study of supercharacters of the finite groups of unipotent upper-triangular matrices, whose representation theory is dictated by the combinatorics of set partitions. In particular, we find a natural set of modules for these groups, whose characters have degrees given by $q$-binomials, and whose decomposition in terms of supercharacters are given by poset binomial coefficients. …”

    3-Homogeneous Groups and Block-Transitive 7–(v, k, 3) Designs by Xiaolian Liao, Guohua Chen, Shangzhao Li

    Published 2017-06-01
    “…The classification of a block-transitive designs is an important subject on algebraic combinatorics. With the aid of MATLAB software, using the classification theorem of 3-homogeneous permutation groups, we look at the classification problem of block-transitive 7–(v, k, 3) design and prove our main theorem: If the automorphism group of a 7–(v, k, 3) design is block-transitive, then it is neither isomorphic to Affine Type Groups nor Almost Simple Type Groups.…”
