A NOTE ON BIGAUSSIAN PELL AND PELL-LUCAS NUMBERS

Journal of Science and Arts, 2021
In this study, we define a new type of Pell and Pell-Lucas numbers which are called biGaussian Pell and biGaussian Pell-Lucas numbers. We also give the relationship between negabiGaussian Pell and Pell-Lucas numbers and bicomplex Pell and Pell-Lucas numbers.

Rich Dad Poor Dad? CEO Private School Background and Firm Risk

European Financial Management, EarlyView.
ABSTRACT We examine the effect of CEO childhood socioeconomic status (SES) on firm risk. Using hand‐collected data on US CEOs' private high‐school attendance as proxy for high‐SES, we find that firms led by high‐SES CEOs exhibit 5.35% lower firm risk. This effect diminishes with CEO tenure, analyst coverage, and institutional ownership, consistent with

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

Ibis, EarlyView.
Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

College Financial Aid Application Frictions

International Economic Review, EarlyView.
ABSTRACT We document that 11 percent of recent U.S. high school graduates did not apply for federal student aid due to difficulty in applying, mistaken beliefs, or lack of awareness. Not applying due to such application frictions negatively predicts college enrollment after controlling for other attributes.

Some Addition Formulas for Fibonacci, Pell and Jacobsthal Numbers

Annales Mathematicae Silesianae, 2019
In this paper, we obtain a closed form for F?i=1k${F_{\sum\nolimits_{i = 1}^k {} }}$, P?i=1k${P_{\sum\nolimits_{i = 1}^k {} }}$and J?i=1k${J_{\sum\nolimits_{i = 1}^k {} }}$ for some positive integers k where Fr, Pr and Jr are the rth Fibonacci, Pell and ...

The Painterly Materiality of Clouds in Antony and Cleopatra and Hamlet

Renaissance Studies, EarlyView.
Abstract This article examines the cloud‐gazing scenes in Antony and Cleopatra and Hamlet through the lens of early modern artistic theory and material practices, particularly the art of limning. Building upon existing philosophical and poetic interpretations of Shakespearean clouds as metaphors for ephemerality and memory, the essay argues that the ...

Incomplete Bivariate Fibonacci and Lucas 𝑝-Polynomials

Discrete Dynamics in Nature and Society, 2012
We define the incomplete bivariate Fibonacci and Lucas 𝑝-polynomials. In the case 𝑥=1, 𝑦=1, we obtain the incomplete Fibonacci and Lucas 𝑝-numbers. If 𝑥=2, 𝑦=1, we have the incomplete Pell and Pell-Lucas 𝑝-numbers.

On $k$-Pell numbers which are sum of two Narayana's cows numbers [PDF]

Mathematica Bohemica
For any positive integer $k\geq2$, let $(P_n^{(k)})_{n\geq2-k}$ be the $k$-generalized Pell sequence which starts with $0,\cdots,0,1$ ($k$ terms) with the linear recurrence P_n^{(k)} = 2P_{n-1}^{(k)}+P_{n-2}^{(k)}+\cdots+P_{n-k}^{(k)}\quad\text{for} n\
