On Wednesday, June 15, 2016, Professor Bezdek gave a colloquium talk at the Mathematics Institute of the University of Pannonia in Veszprem, Hungary.

Professor Károly Bezdek was invited to give a talk in the Geometry Seminar of the Budapest University of Technology and Economics, Budapest, Hungary.  

Conference on Geometric Functional Analysis in Honour of Nicole Tomczak-Jaegermann was held at the University of Alberta, Edmonton AB from May 16-20, 2016. 

Gives a talk on "On non-separable families of positive homothetic convex bodies" on May 5th at the School of Mathematical and Statistical Sciences, The University of Texas Rio Grande Valley, TX.  

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. 

 

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.

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...
