> *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).
