The center of the twisted Heisenberg category, factorial Schur -functions, and transition functions on the Schur graph
Henry Kvinge, Can Ozan Oğuz, Michael Reeks
We establish an isomorphism between the center of the twisted Heisenberg category and the subalgebra of the symmetric functions generated by odd power sums. We give a graphical…
