The Mahonian probability distribution on words is asymptotically normal

E. Rodney Canfield, Svante Janson, Doron Zeilberger

The Mahonian statistic is the number of inversions in a permutation of a multiset with elements of type , . The counting function for this statistic is the $q…

Quasi-random graphs and graph limits

Svante Janson

We use the theory of graph limits to study several quasi-random properties, mainly dealing with various versions of hereditary subgraph counts. The main idea is to transfer the pro…

Graphs where every k-subset of vertices is an identifying set

Sylvain Gravier, Svante Janson, Tero Laihonen +1

Let be an undirected graph without loops and multiple edges. A subset is called \emph{identifying} if for every vertex the intersection of and…

Poset limits and exchangeable random posets

Svante Janson

We develop a theory of limits of finite posets in close analogy to the recent theory of graph limits. In particular, we study representations of the limits by functions of two vari…

Generalized Stirling permutations, families of increasing trees and urn models

Svante Janson, Markus Kuba, Alois Panholzer

Bona [2007+] studied the distribution of ascents, plateaux and descents in the class of Stirling permutations, introduced by Gessel and Stanley [1978]. Recently, Janson [2008+] sho…

On the size of identifying codes in binary hypercubes

Svante Janson, Tero Laihonen

We consider identifying codes in binary Hamming spaces F^n, i.e., in binary hypercubes. The concept of identifying codes was introduced by Karpovsky, Chakrabarty and Levitin in 199…
