A real number, expressed as a decimal, is said to be normal (in the scale of 10) if every combination of digits occurs in the decimal with the proper frequency. If a 1 a 2 … a k is any combination of k digits, and N(t) is the number of times this combination occurs among the first t digits, the condition is that 1

Construction of normal numbers by classified prime divisors of integers

Given an integer d > 2, a d-normal number, or simply a normal number, is a real number whose d-ary expansion is such that any preassigned sequence, of length k > 1, of base d digits from this…

On the Normality of Numbers

A number is normal to the base r if, in its expansion to that base, all possible digit strings of length t are equally frequent for each t . While it is generally believed that many familiar…

The Mysterious World of Normal Numbers

It is known since 1909 that almost all real numbers are normal in every base q and the study of normal numbers has fascinated mathematicians for the past century.

A NOTE ON NORMAL NUMBERS IN MATRIX NUMBER SYSTEMS

Among the properties of number systems mainly investigated are finiteness, periodicity and randomness. In this paper we concentrate on the third property. When dealing with an infinite expansion, one…

ON MODIFYING NORMAL NUMBERS

A real number x is called a normal number (in a base β ≥ 2) if all possible blocks of digits appear with the same asymptotic frequency in the β-ary expansion of x. This notion was introduced by E.…

The sum‐of‐digits function of polynomial sequences

This work answers Gelfond's question and shows the uniform distribution modulo 1 of the sequence ( sq(P(n)))n∈ for ∈ , provided that q is a large enough prime number co-prime with the leading coefficient of P.

The binary digits of a power

Let B(m) denote the number of ones in the binary expansion of the integer m > 1 and let rh(m) = B(mh)/B(m) where h is a positive integer. The maximal order of magnitude of rh(m) is c(h)(og m)(h -)/h…

Absolutely Abnormal Numbers

This paper exhibits a simple construction of a specific irrational (in fact, transcendental) real number that is absolutely abnormal, and easily generalizes to a construction giving uncountably many absolutely abnormal numbers in any open interval.

The Fibonacci Sequence is Normal Base 10

In this paper, we show that the concatenation of the Fibonacci sequence is normal in base 10, meaning every string of a given length, k, occurs as frequently as every other string of length k (there…
