Letter Graphs and Geometric Grid Classes of Permutations
نویسندگان
چکیده
We uncover a connection between two seemingly unrelated notions: lettericity, from structural graph theory, and geometric griddability, the world of permutation patterns. Both these notions capture important properties their respective classes objects. prove that are equivalent in sense class is geometrically griddable if only corresponding inversion graphs has bounded lettericity.

Growth Rates of Geometric Grid Classes of Permutations
Geometric grid classes of permutations have proven to be key in investigations of classical permutation pattern classes. By considering the representation of gridded permutations as words in a trace monoid, we prove that every geometric grid class has a growth rate which is given by the square of the largest root of the matching polynomial of a related graph. As a consequence, we characterise t...
متن کاملF-Permutations induce Some Graphs and Matrices
In this paper, by using the notion of fuzzy subsets, the concept of F-permutation is introduced. Then by applying this notion the concepts of presentation of an F-polygroup, graph of an F-permutation and F-permutation matrices are investigated.
متن کاملGrid Classes and the Fibonacci Dichotomy for Restricted Permutations
We introduce and characterise grid classes, which are natural generalisations of other well-studied permutation classes. This characterisation allows us to give a new, short proof of the Fibonacci dichotomy: the number of permutations of length n in a permutation class is either at least as large as the nth Fibonacci number or is eventually polynomial.
متن کاملCharacterising inflations of monotone grid classes of permutations
We characterise those permutation classes whose simple permutations are monotone griddable. This characterisation is obtained by identifying a set of nine substructures, at least one of which must occur in any simple permutation containing a long sum of 21s.
متن کاملOn Partial Well-Order for Monotone Grid Classes of Permutations
The permutation π of [n] = {1, 2, . . . , n} contains the permutation σ of [k] = {1, 2, . . . , k} (written σ ≤ π) if π has a subsequence of length k order isomorphic to σ. For example, π = 391867452 (written in list, or one-line notation) contains σ = 51342, as can be seen by considering the subsequence 91672 (= π(2), π(3), π(5), π(6), π(9)). A permutation class is a downset of permutations un...
