Title: The finitary symmetric group algebra in characteristic 2
Abstract: In 1996, Baranov and Kleshchev classified maximal ideals in the finitary
symmetric group algebra over fields of characteristic not 2. I will present the
corresponding classification in characteristic 2, which deviates slightly from other
characteristics in final statement, and much more significantly in proof. I will
explain further how this results fits into a deeper, partly conjectural, connection
between prime ideals in the finitary symmetric group algebra and the structure theory of
symmetric tensor categories, in particular the higher Verlinde categories.
