Richard Stanley: Enumerative and Algebraic Combinatorics in the1960’s and 1970’s
In his comment to the previous post by Igor Pak, Joe Malkevitch referred us to a wonderful paper by Richard Stanley on enumerative and algebraic combinatorics in the 1960’s and 1970’s. See also this post on Richard’s memories regarding the … Continue reading
Igor Pak: How I chose Enumerative Combinatorics
Originally posted on Igor Pak's blog:
Apologies for not writing anything for awhile. After Feb 24, the math part of the “life and math” slogan lost a bit of relevance, while the actual events were stupefying to the point…
Oliver Janzer and Benny Sudakov Settled the Erdős-Sauer Problem
Norbert Sauer The news in brief: In the new paper Resolution of the Erdős-Sauer problem on regular subgraphs Oliver Janzer and Benny Sudakov proved that any graph G with vertices and more than edges contains a k-regular subgraph. This bound … Continue reading
