Number of stable digits of any integer tetration
Marco Ripà, Luca Onnis
In the present paper we provide a formula that allows to compute the number of stable digits of any integer tetration base . The number of stable digits, at the g…
On some nested floor functions and their jump discontinuities
Luca Onnis
This paper investigates some particular limits involving nested floor functions. We'll prove some cases and then we'll show a more general result. Then we'll count the discontinuit…
On the general Smarandache's sigma product of digits
Luca Onnis
This paper investigates the behaviour of one of the most famous Smarandache's sequence given by A061076 on oeis. In particular we first study the behaviour of two sequences (A06107…
On a variant of the happy numbers and their generalizations
Luca Onnis
This paper investigates a variant of the famous "happy numbers" sequence, given by A351327 on the oeis. First of all we'll define this integer sequence, and then we'll show some im…
On the -adic valuation of a hyperfactorial
Luca Onnis
In this document will be proved a formula to compute the -adic valuation of a hyperfactorial. We call a hyperfactorial the result of multiplying a given number of consecutive in…
On the 2-adic valuation of (a^b-c^d)
Luca Onnis
In this paper will be proved an inequality regarding . Using this formula it will be possible to have informations about the divisibility of 2 of this function wi…
