Design Theory and some Forbidden Configurations
R. P. Anstee, Farzin Barekat, Zachary Pellegrin
In this paper we relate t-designs to a forbidden configuration problem in extremal set theory. Let 1_t 0_l denote a column of t 1's on top of l 0's. We assume t>l. Let q. (1_t 0_l)…

Design Theory and Some Non-simple Forbidden Configurations
R. P. Anstee, Farzin Barekat
Let 1_k 0_l denote the (k+l)\times 1 column of k 1's above l 0's. Let q. (1_k 0_l) $ denote the (k+l)xq matrix with q copies of the column 1_k0_l. A 2-design S_λ(2,3,v) can be defi…

Composition of transpositions and equality of ribbon Schur Q-functions
Farzin Barekat, Stephanie van Willigenburg
We introduce a new operation on skew diagrams called composition of transpositions, and use it and a Jacobi-Trudi style formula to derive equalities on skew Schur Q-functions whose…
