Pell and Pell–Lucas Numbers as Product of Two Repdigits
Mathematical Notes, 2022Let \( (P_n)_{n\ge 0} \) and \( (Q_n)_{n\ge 0} \) be the sequences of Pell and Pell-Lucas numbers, respectively, given by the linear recurrences: \( P_0=0, P_1=1 \), \( Q_0=2, Q_1=2 \), and \( P_{n+2}=2P_{n+1}+P_n \) and \( Q_{n+2}=2Q_{n+1}+Q_n \) for all \( n\ge 0 \).

Perfect Pell and Pell–Lucas numbers
Studia Scientiarum Mathematicarum Hungarica, 2019Abstract The Pell sequence is given by the recurrence Pn = 2Pn−1 + Pn−2 with initial condition P0 = 0, P1 = 1 and its associated Pell-Lucas sequence is given by the same recurrence relation but with initial condition Q0 = 2, Q1 = 2. Here we show that 6 is the only perfect number appearing in these sequences.

Pell Numbers, Pell–Lucas Numbers and Modular Group
Algebra Colloquium, 2007We show that the matrix A(g), representing the element g = ((xy)2(xy2)2)m (m ≥ 1) of the modular group PSL(2,Z) = 〈x,y : x2 = y3 = 1〉, where [Formula: see text] and [Formula: see text], is a 2 × 2 symmetric matrix whose entries are Pell numbers and whose trace is a Pell–Lucas number. If g fixes elements of [Formula: see text], where d is a square-free

On Pell and Pell−Lucas Hybrid Numbers
Commentationes Mathematicae, 2019In this paper we introduce the Pell and Pell−Lucas hybrid numbers as special kinds of hybrid numbers. We describe some properties of Pell hybrid numbers and Pell−Lucas hybrid numbers among other we give the Binet formula, the character and the generating function for these numbers.

s-PELL AND s-PELL-LUCAS NUMBERS AND THEIR PROPERTIES
Far East Journal of Mathematical Sciences (FJMS), 2017We introduce new families of s-Pell and s-Pell-Lucas numbers and establish certain identities. We also present the recurrence relations and the generating functions for a particular case. © 2017 Pushpa Publishing House, Allahabad, India.

Like Fibonacci and Lucas numbers, the Pell family is ubiquitous. Pell and Pell–Lucas numbers also provide boundless opportunities to experiment, explore, and conjecture; they are a lot of fun for inquisitive amateurs and professionals alike. In this chapter, we formally introduce the family, and cite their occurrences in earlier chapters, as well as ...
