Eigenbasis for a weighted adjacency matrix associated with the projective geometry $B_{q} (n)$

Murali K. Srinivasan

In a recent article "Projective geometries, $Q$ -polynomial structures, and quantum groups" Terwilliger (arXiv:2407.14964) defined a certain weighted adjacency matrix, depending on…

Subspaces, subsets, and Motzkin paths

Jonathan D. Farley, Murali K. Srinivasan

We define a map from subspaces to Motzkin paths and show that the inverse image of every path is a disjoint union of symmetric Boolean subsets yielding an explicit symmetric Boolea…

Note on Doron Zeilberger's paper: $(2 5)$ proofs that $(k n) \leq (k + 1 n)$ if $k < n /2$

Murali K. Srinivasan

We present yet another algebraic proof of the unimodality of the binomial coefficients.
