On decompositions of a cyclic permutation into a product of a given number of permutations

Functional Analysis and Its Applications, 2015
The investigation of decompositions of a permutation into a product of permutations satisfying certain conditions plays a key role in the study of meromorphic functions or, equivalently, branched coverings of the 2-sphere; it goes back to A. Hurwitz’ work in the late nineteenth century. In 2000 M. Bousquet-Melou and G.

Products of cyclic permutations

Publicationes Mathematicae Debrecen, 2022
The author considers the case when a cyclic permutation of length \(n\) is a product of \(r\) cyclic permutations of lengths \(n_ 1,n_ 2,\ldots,n_ r\). In this case \[ n\leq 1-r+\sum^ r_{i=1} n_ i. \] In particular, the author studies the extremal case where \(n_ 1,\ldots,n_ r\) are such that \(n=1-r+\sum^ r_{i=1} n_ i.\) He proves conditions ...

Long-Haul DMD-Unmanaged 6-Mode-Multiplexed Transmission Employing Cyclic Mode-Group Permutation

Optical Fiber Communications Conference and Exhibition, 2020
We demonstrate a long-haul 6-mode-multiplexed WDM transmission with a record reach of 3250 km. Newly-developed mode-group permutation technique mitigated modal-dispersion-impact by > 70%.

The cyclic structure of random permutations

Mathematical Notes of the Academy of Sciences of the USSR, 1975
Letα r denote the number of cycles of length r in a random permutation, taking its values with equal probability from among the set Sn of all permutations of length n. In this paper we study the limiting behavior of linear combinations of random permutationsα 1, ...,α r having the form
