Cannon–Thurston maps for hyperbolic free group extensions
Israel Journal of Mathematics, 2015This paper gives a detailed analysis of the Cannon–Thurston maps associated to a general class of hyperbolic free group extensions. Let F denote a free group of finite rank at least 3 and consider a convex cocompact subgroup Γ ≤ Out(F), i.e.

Group Robust Preference Optimization in Reward-free RLHF
Neural Information Processing SystemsAdapting large language models (LLMs) for specific tasks usually involves fine-tuning through reinforcement learning with human feedback (RLHF) on preference data.

Free group $C^*$-algebras associated with $\ell_p$
, 2012For every $p\geq 2$, we give a characterization of positive definite functions on a free group with finitely many generators, which can be extended to the positive linear functionals on the free group $C^*$-algebra associated with the ideal $\ell_p ...

Strongly solid group factors which are not interpolated free group factors
, 2009We give examples of non-amenable infinite conjugacy classes groups Γ with the Haagerup property, weakly amenable with constant Λcb(Γ) = 1, for which we show that the associated II1 factors L(Γ) are strongly solid, i.e.

Ergodic Theory and Dynamical Systems, 2008
This paper introduces Markov chains and processes over non-abelian free groups and semigroups. We prove a formula for the f-invariant of a Markov chain over a free group in terms of transition matrices that parallels the classical formula for the entropy
