Upcoming CARMA Events


  • CARMA COLLOQUIUM
  • Speaker: Alan Haynes, University of York
  • Title: Quasicrystals and Diophantine approximation
  • Location: V205, Mathematics Building (Callaghan), The University of Newcastle
  • Time and Date: 4:00 pm, Thu, 10th Sep 2015
  • Abstract:
    In this talk we will begin with a brief history of the mathematics of aperiodic tilings of Euclidean space, highlighting their relevance to the theory of quasicrystals. Next we will focus on an important collection of point sets, cut and project sets, which come from a dynamical construction and provide us with a mathematical model for quasicrystals. After giving definitions and examples of these sets, we will discuss their relationship with Diophantine approximation, and show how the interplay between these two subjects has recently led to new results in both of them.

  • CARMA NUMBER THEORY SEMINAR
  • Speaker: Dr Faustin Adiceam, University of York
  • Title: Rational approximation and arithmetic progressions
  • Location: V205, Mathematics Building (Callaghan), The University of Newcastle
  • Time and Date: 3:00 pm, Tue, 20th Oct 2015
  • Abstract:
    We discuss problems of approximation of an irrational by rationals whose numerators and denominators lie in prescribed arithmetic progressions. Results are both, on the one hand, from a metrical and a non-metrical point of view, and on the other, from an asymptotic and also a uniform point of view. The principal novelty of this theory is a Khintchine-type theorem for uniform approximation in this setup. Time permitting some applications of this work will be discussed.
  • Details to be confirmed.

  • CARMA COLLOQUIUM
  • Speaker: Dr Faustin Adiceam, University of York
  • Title: How far can you see in a forest?
  • Location: V205, Mathematics Building (Callaghan), The University of Newcastle
  • Time and Date: 4:00 pm, Thu, 22nd Oct 2015
  • Abstract:

    We will be answering the following question raised by Christopher Bishop:

    'Suppose we stand in a forest with tree trunks of radius $r > 0$ and no two trees centered closer than unit distance apart. Can the trees be arranged so that we can never see further than some distance $V < \infty$, no matter where we stand and what direction we look in? What is the size of $V$ in terms of $r$?'

    The methods used to study this problem involve Fourier analysis and sharp estimates of exponential sums.
