Hypermaps with hyperedges of length at most
Robert Cori, Gábor Hetyei
We study the computation of our recently introduced Whitney polynomial and the enumeration of the spanning hypertrees for hypermaps whose hyperedges have length at most . This i…

A Whitney polynomial for hypermaps
Robert Cori, Gábor Hetyei
We introduce a Whitney polynomial for hypermaps and use it to generalize the results connecting the circuit partition polynomial to the Martin polynomial and the results on several…

On reduced unicellular hypermonopoles
Robert Cori, Gábor Hetyei
The problem of counting unicellular hypermonopoles by the number of their hyperedges is equivalent to describing the cycle length distribution of a product of two circular permutat…
