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.

Published in 2020 at "Afrika Matematika"

DOI: 10.1007/s13370-020-00823-z

Abstract: We prove three new theta function identities for the continued fraction H ( q ) defined by $$\begin{aligned} H(q):=q^{1/8}-\frac{q^{7/8}}{1-q}_{+}\frac{q^2}{1+q^2}_{-}\frac{q^3}{1-q^3}_{+}\frac{q^4}{1+q^4}_{- \cdots }, \vert q\vert read more here.

Published in 2017 at "Journal of Number Theory"

DOI: 10.1016/j.jnt.2016.11.024

Abstract: Abstract In this paper, we define some new continued fraction sequences towards Euler's constant and two related inequalities. We also present some numerical simulations to demonstrate the superiority of the optimal new sequences over new… read more here.

Published in 2021 at "Journal of Number Theory"

DOI: 10.1016/j.jnt.2021.07.032

Abstract: We provide several asymptotic expansions of the prime counting function $\pi(x)$ and related functions. We define an {\it asymptotic continued fraction expansion} of a complex-valued function of a real or complex variable to be a… read more here.

Published in 2023 at "Journal of Difference Equations and Applications"

DOI: 10.1080/10236198.2023.2204979

Abstract: We present two (inequivalent) polynomial continued fraction representations of the number eπ with all their elements in Q; no such representation was seemingly known before. More generally, a similar result for erπ is obtained for… read more here.

Published in 2017 at "Filomat"

DOI: 10.2298/fil1713975a

Abstract: On Page 36 of his ``lost" notebook, Ramanujan recorded four $q$-series representations of the famous Rogers-Ramanujan continued fraction. In this paper, we establish two $q$-series representations of Ramanujan's  continued fraction found in his ``lost" notebook.… read more here.

Published in 2021 at "Mathematics"

DOI: 10.3390/math9030255

Abstract: We investigate the efficiency of several types of continued fraction expansions of a number in the unit interval using a generalization of Lochs theorem from 1964. Thus, we aim to compare the efficiency by describing… read more here.
