Euler's factorial series, Hardy integral, and continued fractions

چکیده
We study p-adic Euler's series Ep(t)=∑k=0∞k!tk at a point pa, a∈Z≥1, and use Padé approximations to prove lower bound for the absolute value of expression cEp(±pa)−d, where c,d∈Z. It is interesting that same polynomials which p-adically converge Ep(t), approach Hardy integral H(t)=∫0∞e−s1−tsds on Archimedean side. This connection used with trick analytic continuation when deducing an numerator polynomial needed in derivation |cEp(±pa)−d|p. Furthermore, we present interconnection between E(t) H(t) via continued fractions.

Beta-continued Fractions over Laurent Series
The present paper is devoted to a new notion of continued fractions in the field of Laurent series over a finite field. The definition of this kind of continued fraction algorithm is based on a general notion of number systems. We will prove some ergodic properties and compute the Hausdorff dimensions of bounded type continued fraction sets.
متن کاملContinued Fractions of Tails of Hypergeometric Series
The tails of the Taylor series for many standard functions such as arctan and log can be expressed as continued fractions in a variety of ways. A surprising side effect is that some of these continued fractions provide a dramatic acceleration for the underlying power series. These investigations were motivated by a surprising observation about Gregory’s series. Gregory’s series for π, truncated...
متن کاملSpecialisation and Reduction of Continued Fractions of Formal Power Series
We discuss and illustrate the behaviour of the continued fraction expansion of a formal power series under specialisation of parameters or their reduction modulo p and sketch some applications of the reduction theorem here proved.

We investigate when an algebraic function of the form φ(λ) = −B(λ)+ √ R(λ) A(λ) , where R(λ) is a polynomial of odd degree N = 2g + 1 with coefficients in C, can be written as a periodic α-fraction of the form
متن کاملContinued Fractions and Gaps
Given a continued fraction, we construct a certain function that is discontinuous at every rational number p/q. We call this discontinuity the “gap”. We then try to characterize the gap sizes, and find, to the first order, the size is 1/q2, and that, for higher orders, the gap appears to be perfectly ’randomly’ distributed, in that it is Cauchy-dense on the unit square, and thus, this function ...
