Pattern-avoiding even and odd Grassmannian permutations
Juan B. Gil, Jessica A. Tomasko
In this paper, we investigate pattern avoidance of parity restricted (even or odd) Grassmannian permutations for patterns of sizes 3 and 4. We use a combination of direct counting…

Restricted Grassmannian permutations
Juan B. Gil, Jessica A. Tomasko
A permutation is called Grassmannian if it has at most one descent. In this paper, we investigate pattern avoidance and parity restrictions for such permutations. As our main resul…

Fibonacci colored compositions and applications
Juan B. Gil, Jessica A. Tomasko
We study compositions whose parts are colored by subsequences of the Fibonacci numbers. We give explicit bijections between Fibonacci colored compositions and several combinatorial…
