Tel Aviv University
Dear all,
This week at the Horowitz seminar on Probability, Ergodic Theory and
Dynamical Systems at Tel Aviv University we are happy to have:
Speaker: Ross Pinsky, Technion
Title: Probabilistic and Combinatorial Aspects of the Card-Cyclic to
Random Insertion Shuffle
Date: Monday, April 23
Time: 14:30
Place: Schreiber 309
Consider a permutation pi in S_n as a deck of cards numbered from 1 to n
and laid out in a row, where pi(j) denotes the number of the card that is
in the j-th position from the left. We study some probabilistic and
combinatorial aspects of the shuffle on S_n defined by removing and then
randomly reinserting each of the n cards once, with the removal and
reinsertion being performed according to the original left to right order
of the cards.
The novelty here in this nonstandard shuffle is that every card is removed
and reinserted exactly once. The bias that remains turns out to be quite
strong, and takes on some unusual forms.
