چکیده
i iii Acknowledgment My deepest gratitude goes to my advisor, Ira Gessel, without whom this work would not be possible; I would like to thank him for his generosity in sharing his insight and time with me, and his constant patience and encouragement. It was and will always be my pleasure to work with him.

132-avoiding two-stack sortable permutations, Fibonacci numbers, and Pell numbers
We describe the recursive structures of the set of two-stack sortable permutations which avoid 132 and the set of two-stack sortable permutations which contain 132 exactly once. Using these results and standard generating function techniques, we enumerate two-stack sortable permutations which avoid (or contain exactly once) 132 and which avoid (or contain exactly once) an arbitrary permutation ...
متن کامل2-stack Pushall Sortable Permutations
In the 60’s, Knuth introduced stack-sorting and serial compositions of stacks. In particular, one significant question arise out of the work of Knuth: how to decide efficiently if a given permutation is sortable with 2 stacks in series? Whether this problem is polynomial or NP-complete is still unanswered yet. In this article we introduce 2-stack pushall permutations which form a subclass of 2-...
متن کاملMulti-statistic enumeration of two-stack sortable permutations
Using Zeilberger’s factorization of two-stack-sortable permutations, we write a functional equation — of a strange sort — that defines their generating function according to five statistics: length, number of descents, number of right-to-left and left-to-right maxima, and a fifth statistic that is closely linked to the factorization. Then, we show how one can translate this functional equation ...
متن کاملSorted and or sortable permutations
In his Ph D thesis Julian West studied in depth a map that acts on permutations of the symmetric group Sn by partially sorting them through a stack The main motivation of this paper is to characterize and count the permutations of Sn which we call sorted permutations This is equivalent to counting preorders of increasing binary trees We rst nd a local characterization of sorted permutations The...
متن کاملOn the Stack Sortable and Pushpopable Permutations
This work proposes an O(log n) time parallel algorithm for testing whether a permutation is stack sortable or not by O(n) processors under the PRAM EREW computational model. Additionally, the number of permutations which are both stack sortable and pushpopable is also discussed, and an equality is finally obtained, which combines n!, 2, Cn, and Un together where Cn is the Catalan number and Un ...
متن کاملSorting Permutations on Two Parallel Stacks
We give a new combinatorial proof, based on stack graphs, for the characterization by forbidden subsequences of the permutations which are sortable on two parallel stacks. Some remarks about the permutations sortable on parallel queues are also made.
