Counting involutory, unimodal, and alternating signed permutations

In this work we count the number of involutory, unimodal, and alternating elements of the group of signed permutations Bn, and the group of even-signed permutations Dn. Recurrence relations, generating functions, and explicit formulas of the enumerating sequences are given. © 2006 Elsevier B.V. All rights reserved. MSC: primary: 05A15; secondary: 05A19; 05A05

Counting Permutations by Alternating Descents

We find the exponential generating function for permutations with all valleys even and all peaks odd, and use it to determine the asymptotics for its coefficients, answering a question posed by Liviu Nicolaescu. The generating function can be expressed as the reciprocal of a sum involving Euler numbers: ( 1− E1x + E3 x3 3! − E4 x4 4! + E6 x6 6! − E7 x7 7! + · · · )−1 , (∗) where ∑∞ n=0Enx n/n! ...

Counting permutations by their alternating runs

We find a formula for the number of permutations of [n] that have exactly s runs up and down. The formula is at once terminating, asymptotic, and exact. The asymptotic series is valid for n→∞, uniformly for s (1 − )n/ logn ( > 0). © 2007 Elsevier Inc. All rights reserved.

Pairings and Signed Permutations

Identity (1) is easy to prove: note that the left side is a convolution, so multiply it by xn , sum, and recognize the square of a binomial series. But a combinatorial interpretation of the same identity is not so easy to find. In [3], M. Sved recounts the story of the identity and its combinatorial proofs. She relates how, after she challenged her readers (in a previous article) to find a comb...

Unimodal Permutations and Almost-Increasing Cycles

In this paper, we establish a natural bijection between the almost-increasing cyclic permutations of length n and unimodal permutations of length n − 1. This map is used to give a new characterization, in terms of pattern avoidance, of almostincreasing cycles. Additionally, we use this bijection to enumerate several statistics on almost-increasing cycles. Such statistics include descents, inver...
