On Pattern Avoiding Alternating Permutations

Joanna N. Chen, William Y. C. Chen, Robin D. P. Zhou

An alternating permutation of length $n$ is a permutation $π = π_{1} π_{2} ... π_{n}$ such that $π_{1} < π_{2} > π_{3} < π_{4} > ...$ . Let $A_{n}$ denote set of alternating permutations of ${1,2,...…
