The approximants to regular continued fractions constitute best approximations to the numbers they converge to in two ways known as the first and the second kind. This property of continued fractions provides a solution to Gosper's problem of the bat

This article closes a trilogy on the existence of singular functions with non-zero finite derivatives. In two previous papers, the authors had exhibited a continuous strictly increasing singular function from [ 0 , 1 ] into [ 0 , 1 ] with a derivativ

The authors had exhibited in a previous paper a continuous strictly increasing singular function from [ 0 , 1 ] into [ 0 , 1 ] with a derivative that takes non-zero finite values at the points of an uncountable set. In this article, the construction

This paper exhibits, for the first time in the literature, a continuous strictly increasing singular function with a derivative that takes non-zero finite values at some points. For all the known “classic” singular functions—Cantor’s, Helling

It is widely accepted in the literature about the classical Cournot oligopoly model that the loss of quasi-competitiveness islinked, in the long run as new firms enter the market, to instability of the equilibrium. In this paper, though, we present a

What do the three names in the title have in common? The purpose of this paper is to relate them in a new and, hopefully, interesting way. Starting with the Fibonacci numeration system — also known as Zeckendorff's system — we will pose ourselves

In 1952 F. Riesz and Sz.-Nagy published an example of a monotonic continuous function whose derivative is zero almost everywhere, that is to say, a singular function. Besides, the function was strictly increasing. Their example was built as the limit

Theorem 1 of Euler's paper of 1737 'Variae Observationes Circa Series Infinitas', states the astonishing result that the series of all unit fractions whose denominators are perfect powers of integers minus unity has sum one. Euler attributes the Theo

Minkowski's ?( x ) function can be seen as the confrontation of two number systems: regular continued fractions and the alternated dyadic system. This way of looking at it enables us to prove that its derivative, when it exists in a wide sense, can o
