Sign Up to like & getrecommendations! Published in 2022 at "Periodica Mathematica Hungarica"
DOI: 10.1007/s10998-021-00444-4
Abstract: We attempt to investigate a two-dimensional Gauss–Kuzmin theorem for Rényi-type continued fraction expansions. More precisely, our focus is to obtain specific lower and upper bounds for the error term considered which imply the convergence rate… read more here.
