Soft packings, nested clusters, and condensed matter

American Institute of Mathematics, San Jose, California 
19-23 September, 2016 

Organizers: Karoly Bezdek, Nikolai Dolbilin, Egon Schulte and Marjorie Senechal

This workshop, sponsored by AIM and the NSF, will be devoted to modeling the geometry of condensed matter. The workshop will focus on "soft packing" and "nested clustering" phenomena in discrete geometric structures and their applications to understanding the internal atomic structure of solids and fluids. In particular, the workshop seeks to integrate the theories of tilings, coverings, and packings, and to develop new discrete geometric concepts and tools needed to study aperiodic structures such as aperiodic crystals.

Gives an invited talk at the Geometry Seminar of the Courant Institute of Mathematical Sciences, New York University.

The interview is part of GSA's initiative to highlight inspirational stories of U of C graduate student.

Give invited talks at the special session on New Developments in Discrete and Intuitive Geometry (Dedicated to the 75th birthday of Wlodzimierz Kuperberg) that took place during the 2016 Spring Southeastern Sectional Meeting held at the University of Georgia, Athens, GA.

Welcome to the University of Calgary's Centre for Computational & Discrete Geometry (CCDG), an academic research centre housed within the Department of Mathematics & Statistics and supported by the Canada Research Chairs Program, Canada Foundation for Innovation, Natural Sciences and Engineering Research Council of Canada, Faculty of Science and the Department of Mathematics and Statistics.

Title: On the covering index of convex bodies 

Authors: Károly Bezdek (U of C) and Muhammad A. Khan (U of C)

Journal: Aequationes Mathematicae 


Abstract: Covering a convex body by its homothets is a classical notion in discrete geometry that has resulted in a number of interesting and long-standing problems. Swanepoel introduced the covering parameter of a convex body as a means of quantifying its covering properties. In this paper, we introduce two relatives of the covering parameter called covering index and weak covering index, which upper bound well-studied quantities like the illumination number, the illumination parameter and...
