Counting formulas and bijections of nondecreasing 2-noncrossing trees
(Electronic Journal of Mathematics, 2024-07-02)In this paper, we introduce nondecreasing 2-noncrossing trees and enumerate them according to their number of vertices, root degree, and number of forests. We also introduce nondecreasing 2-noncrossing increasing trees ...
