*Title:* An inhomogeneous q-deformation of the Tsetlin Library

*Abstract: *The Tsetlin library is a random-to-top shuffle process on 
permutations. A q-deformation using the Hecke algebra can also be 
implemented on flags over the finite field $\mathbb{F}_q^n$. The 
semigroup underlying the random-to-top Markov chain on flags is a left 
regular band, which provides a method to compute the stationary 
distribution and eigenvalues. We consider a further generalisation by 
introducing inhomogeneous rates. This is work in collaboration with 
Sarah Brauner, Jan de Gier and Anne Schilling (arXiv:2601.21195).
