Bijection between Increasing Binary Trees and Rook Placements on Double Staircases

Bishal Deb

In this paper, we shall construct a bijection between rook placements on double staircases (introduced by Josuat-Vergès in 2017) and increasing binary trees. We introduce two subcl…

Continuously Increasing Subsequences of Random Multiset Permutations

Alexander Clifton, Bishal Deb, Yifeng Huang +2

For a word $π$ and integer $i$ , we define $L^{i} (π)$ to be the length of the longest subsequence of the form $i (i + 1) \dots j$ , and we let $L (π) := max_{i} L^{i} (π)$ . In this paper we esti…
