An Insertion Algorithm for Diagram Algebras
We generalize the Robinson-Schensted-Knuth algorithm to the insertion of two row arrays of multisets.
This generalization leads to an algorithm from partition diagrams to pairs of a standard tableau and a standard
multiset tableau of the same shape, which has the remarkable property that it is well-behaved with respect to
restricting a representation to a subalgebra. This insertion algorithm matches recent representation-theoretic
results of Halverson and Jacobson.
