The story goes almost two decades back. I was studying computer engineering in College of Engineering Pune. Prof Vinayak Joshi had recently joined COEP and had research interest in discrete mathematic, especially Lattices. He needed some software for exploring some patterns in graphs. Matlab, though almost three decades old by then, was new to us and quite expensive. He approached my scholar friend Amit Bose and requested him to write a program for exploring the desired graph patterns. If ...| Walking with the Elephants

…appears to be four (an infinite improvement). I coauthored a paper with Gary Greaves, whose recent paper Edge-signed graphs with smallest eigenvalue greater than -2 also saw contributions from Jack Koolen and Akhiro Munemasa. They both have an Erdős number of two (each via Chris Godsil, who is an Erdős coauthor), making Gary a three ...Continue reading ‘My Erdős number…’ »| Modulo Errors
