I never meet neither know Keith Hardie or his mathematics, but taking of true gentlemen and talented mathematician, I always remember Max Kelly. On 24/05/14 02:59, Ross Street wrote:
I agree with Fred and Marco. Keith Hardie was one of a vanishing breed of true gentlemen.
When I visited Cape Town in the early 1980s, we discovered we had a common interest in diagrams of interlocking sequences (so called by TCT (Terry) Wall). Keith?s interlocking sequences arose from homotopy groups, mine from homology. He kept encouraging me until I wrote up a result I had while writing, but did not include in, my thesis. I really enjoyed revisiting that result and improving some techniques.
That first visit to South Africa and an evening at Keith?s home left a lasting impression on me. We only met a few times after that, the last being CT2009.
It is very sad news, Peter. Please convey my condolences to the family.
