HIGHLIGHTS
- who: Quasisymmetric functions and colleagues from the FPSAC , Paris, France Department of Mathematics, Serra Mall, Stanford University, CA, USA have published the paper: A Hopf-power Markov chain on compositions, in the Journal: (JOURNAL)
- what: The example in this paper has as its states the non-polynomial basis {FI } of fundamental quasisymmetric functions. The aim of this section is to prove that the coproduct-then-product operator on the algebra of quasisymmetric functions encodes the changes in descent set of a deck of distinct cards under riffle-shuffling.
