Transferred -structures and a classification of binary brackets for finite-dimensional skew-gentle algebras
Zixu Li, Liyu Liu, Lingchao Meng
We construct a transferred -structure on the shifted Chouhy--Solotar cochain complex of a finite-dimensional skew-gentle algebra and give explicit basis-level formulas fo…

Lift-Free Approaches to Random Rotation Number and Numerical Approximation
Zixu Li, Simon Lloyd
We study the random rotation number for random circle homeomorphisms. We introduce two new definitions of the random rotation number that can be stated without reference to any cho…

Periodicity and Rotation Number for Random Circle Homeomorphisms
Zixu Li, Simon Lloyd
We study discrete-time random dynamical systems where each fibre map is an orientation-preserving homeomorphism of the circle. We prove that the existence of a random periodic cycl…
