André Permutations, Right-To-Left and Left-To-Right Minima
Abstract.
We provide enumerative results concerning right-to-left minima and
left-to-right minima in André permutations of the first and second
kind.
For both of the two kinds, the distribution of right-to-left and
left-to-right minima is the same. We provide generating functions and
associated asymptotic results. Our approach is based on the tree-structure of André permutations.
