    On the Polymatroidal Property of Monomial Ideals with a View towards Orderings of Minimal Generators
  • School
    MATHEMATICS

    We prove that a monomial ideal $I$ generated in a single degree, is polymatroidal
    if and only if it has linear quotients with respect to the lexicographical ordering of the minimal generators induced by every ordering of variables. We also
    conjecture that the polymatroidal ideals can be characterized with
    linear quotients property with respect to the reverse
    lexicographical ordering of the minimal generators induced by every
    ordering of variables. We prove our conjecture in many special
    cases. ...

    The (almost) Pointless Geometries

    School
    MATHEMATICS

    Many philosophical schools of mathematics reject the notion of infinity, and restrict attention to finite structures and objects. At first sight it would seem that they could not deal at all with classical geometry, since its usual entities (segments, lines, circles) all consist of infinitely many points. To bypass the problem, modern mathematics has developed a number of finite versions of Euclidean and non Euclidean geometries, which raise many subtle and difficult problems, the solutions of some of which have even led to a couple of Fields medals. ...
