[DissKoll] DissKoll, May 7, 2009, Markus Kuba (Reminder)

[Klemens Katterbauer]

Dear visitors of the DissKoll (Dissertantenkolloquium),

A reminder of Thursday's first talk of the DissKoll. Markus Kuba (Technical
University of Vienna, DMG) will talk about “Stirling permutations and
trees”.


Abstract: Stirling permutations were introduced by Gessel and Stanley. A
Stirling permutation is a permutation of the multiset $\{1,1,2,2,dots,n,n\}$
such that for each $i$, the elements occuring between the two occurrences of
$i$ are larger than $i$. Stirling permutations are naturally related
to second order Eulerian numbers and to Stirling polynomials.

We will present generalized Stirling permutations and relate them with
certain families of increasing trees. The close relationship between
Stirling permutations and trees allows to analyze parameters in Stirling
permutations by analyzing their counterparts in the corresponding tree
family. Furthermore, several parameters in random Stirling permutations
can be described by so-called P\'olya-Eggenberger urn models. We present
several results obtained using combinatorial and probabilistic methods.



Thursday, May 7, 2009, 17:15, Room C 2.09
Coffee and cakes served from 17:00 in the Common Room C 2.06
