3. Forced Grading

    1. Problem 3.1.

      [Scott] Is it true for a Schur algebra $A$, in particular $A = S(5, 5)$ in characteristic 2, that $A \cong \tilde{\operatorname{gr}}A$, the forced graded algebra in the sense of Parshall–Scott, obtained from the radical series of the corresponding $q$-Schur algebra?
