Floor and ceiling functions for Pell numbers [PDF]
Notes on Number Theory and Discrete MathematicsThe analytical study of the Pell number and the role of floor and ceiling functions into their computation is examined. Closed expressions of Pell numbers were initially derived using Binet's formula, followed by an asymptotic behavior study of the ...

ON THE PRIMES IN FLOOR FUNCTION SETS
Bulletin of the Australian Mathematical Society, 2022 AbstractLet $[t]$ be the integral part of the real number t and let $\mathbb {1}_{{\mathbb P}}$ be the characteristic function of the primes. Denote by $\pi _{\mathcal {S}}(x)$ the number of primes in the floor function set $\mathcal {S}(x) := \{[{x}/{n}] : 1\leqslant n\leqslant x\}$ and by $S_{\mathbb {1}_{{\mathbb P}}}(x)$ the number of ...

Dilated Floor Functions That Commute Sometimes
The PUMP Journal of Undergraduate Research, 2019 We explore the dilated floor function fa(x)= ⌊ax⌋ and its commutativity with functions of the same form. A previous paper found all a and b such that fa and fb commute for all real x. In this paper, we determine all x for which the functions commute for a particular choice of a and b.

Syntactic Complexity of R- and J-Trivial Regular Languages [PDF]
, 2013 The syntactic complexity of a regular language is the cardinality of its syntactic semigroup. The syntactic complexity of a subclass of the class of regular languages is the maximal syntactic complexity of languages in that class, taken as a function of ...
