| | Professor H. Kharaghani from the Department of Mathematics and Computer Science, University of Lethbridge, Canada, is spending his sabbatical leave at the School of Mathematics of IPM during January 5 to August 30, 2008.
Kharaghani has visited IPM several times and has been one of the organizers of:
-
Workshop on Combinatorics, Linear Algebra & Graph Coloring,
August 9-14, 2003
-
IPM Combinatorics II: Design Theory, Graph Theory, and Computational Methods,
April 22-27, 2007
held at the School of Mathematics of IPM.
In 2004, Hadi Kharaghani joint with Behruz Tayfeh-Rezaie, a faculty member of the School of Mathemaics, constructed a Hadamard matrix of order 428 while he was on study leave from the University of Lethbridge, and this construction had a great reflection over the world of mathematics.
