Snow Leopard Permutations and Their Even and Odd Threads [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2016
Caffrey, Egge, Michel, Rubin and Ver Steegh recently introduced snow leopard permutations, which are the anti-Baxter permutations that are compatible with the doubly alternating Baxter permutations. Among other things, they showed that these permutations

The Brownian limit of separable permutations [PDF]

open access: yesAnnals of Probability, 2017
We study random uniform permutations in an important class of pattern-avoiding permutations: the separable permutations. We describe the asymptotics of the number of occurrences of any fixed given pattern in such a random permutation in terms of the ...

Arc Permutations [PDF]

open access: yesJournal of Algebraic Combinatorics, 2013
Arc permutations and unimodal permutations were introduced in the study of triangulations and characters. This paper studies combinatorial properties and structures on these permutations. First, both sets are characterized by pattern avoidance.

On the sub-permutations of pattern avoiding permutations

open access: yesDiscrete Mathematics, 2014
There is a deep connection between permutations and trees. Certain sub-structures of permutations, called sub-permutations, bijectively map to sub-trees of binary increasing trees.

SIF Permutations and Chord-Connected Permutations [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2014
A stabilized-interval-free (SIF) permutation on [n], introduced by Callan, is a permutation that does not stabilize any proper interval of [n]. Such permutations are known to be the irreducibles in the decomposition of permutations along non-crossing ...

Interlocked permutations [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2018
The zero-error capacity of channels with a countably infinite input alphabet formally generalises Shannon's classical problem about the capacity of discrete memoryless channels. We solve the problem for three particular channels.

The Dirac Equation, Mass and Arithmetic by Permutations of Automaton States [PDF]

open access: yesEntropy
The cornerstones of the Cellular Automaton Interpretation of Quantum Mechanics are its underlying ontological states that evolve by permutations. They do not create would-be quantum mechanical superposition states.

Palindromic permutations and generalized Smarandache palindromic permutations

open access: yesviXra, 2006
The idea of left(right) palindromic permutations(LPPs,RPPs) and left(right) generalized Smarandache palindromic permutations(LGSPPs,RGSPPs) are introduced in symmetric groups S_n of degree n.

Twin-width and permutations [PDF]

open access: yesLog. Methods Comput. Sci., 2021
Inspired by a width invariant on permutations defined by Guillemot and Marx, Bonnet, Kim, Thomass\‘e, and Watrigant introduced the twin-width of graphs, which is a parameter describing its structural complexity.

To permute or not to permute [PDF]

open access: yesBioinformatics, 2006
Abstract Permutation test is a popular technique for testing a hypothesis of no effect, when the distribution of the test statistic is unknown. To test the equality of two means, a permutation test might use a test statistic which is the difference of the two sample means in the univariate case.
