Query: Brauer Configuration Algebras and Matrix Problems to Categorify Integer
  Sequences   Bijections between invariants associated to indecomposable projective modules
over some suitable Brauer configuration algebras and invariants associated to
solutions of the Kronecker problem and the four subspace problem are used to
categorify integer sequences in the sense of Ringel and Fahr. Dimensions of the
Brauer configuration algebras and their corresponding centers involved in the
different processes are given as well.
