We try to read every blog post that goes through Mathblogging.org. For the Weekly Picks, we collect posts in one category from last week to give you an impression of what the mathematical blogosphere has to offer. (Read this for more information on this change.)

Last week, we focused on “Applied” blogs.

Reviews, Exposition, etc.

  • Mathbabe wonders what data science PhDs are worth when they can’t access the data from private companies.
  • At Algorithms, game theory, social choice [...] etc, Haris Aziz gives a shout out to his co-author winning “best presentation by a young scientist” at the Matching Markets Conference.

Research

  • Regularize can stop being bothered by three problems in complexity — RIP & NSP are NP-hard and homotopy for l1 has exponential growth.
  • Nathaniel Johnston shares some notes on norms and dual norms in finite dimensional Hilbert spaces.
