Norms Of Hankel-Hessenberg and Toeplitz-Hessenberg Matrices Involving Pell and Pell-Lucas Numbers [PDF]

, 2016
We derive some sum formulas for the squares of Pell and Pell-Lucas numbers. We construct Hankel-Hessenberg andToeplitz-Hessenberg matrices whose entries in the first column are HHP = aij , ij i j a P = ; Q HH =   ij a , ij i j a Q =and ...

College Financial Aid Application Frictions

International Economic Review, Volume 67, Issue 3, Page 1015-1041, August 2026.
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.

Bipartite Graphs Associated with Pell, Mersenne and Perrin Numbers

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In this paper, we consider the relationships between the numbers of perfect matchings (1-factors) of bipartite graphs and Pell, Mersenne and Perrin Numbers.

Interpreting the Intensity of Vocal Emotions Across Cultures

Scandinavian Journal of Psychology, Volume 67, Issue 4, Page 983-1003, August 2026.
ABSTRACT Intensity is a fundamental dimension of emotions that affects their perception. However, theoretical and empirical studies on intensity, particularly in the vocal domain, remain limited. Furthermore, research on the effects of emotional dimensions (e.g., arousal, valence, and basicness) on intensity ratings remains sparse.

t-balancing numbers, Pell numbers and square triangular numbers [PDF]

, 2017
Let t ≥ 2 be an integer. In this work we get all integer solutions of the Diophantine equation 8r 2 + 8tr + 1 = y 2 in order to determine the general terms of all t−balancing numbers for which 2t 2 − 1 is prime. Later we obtain some formulas for the sums

On the Norms of Toeplitz Matrices with the Pell, Pell-Lucas and Modified Pell Numbers

Journal of Engineering Technology and Applied Sciences, 2016
This paper deals with the usual Pell, Pell-Lucas and Modified Pell numbers and Toeplitz matrices. First, the Toeplitz matrices whose entries are the usual Pell, Pell-Lucas and Modified Pell numbers are constructed, and then the Frobenius, row and column norms of such matrices are computed.

On the sequences of $(q,k)$-generalized Fibonacci numbers [PDF]

Mathematica Bohemica
We consider a new family of recurrence sequences, the $(q,k)$-generalized Fibonacci numbers. These sequences naturally extend the well-known sequences of $k$-generalized Fibonacci numbers and generalized $k$-order Pell numbers.

ON SOME INEQUALITIES AND HANKEL MATRICES INVOLVING PELL, PELL-LUCAS NUMBERS [PDF]

, 2013
In [4], the authors defined Toeplitz and Hankel matrices with Pell numbers and gave bounds for the spectral norms of them. In this study, we define Hankel matrices involving the Pell, Pell-Lucas and modified Pell sequences and investigate some properties

On a new family of the generalized gauss k-pell-lucas numbers and their polynomials [PDF]

, 2022
In this paper, we generalize the known Gauss Pell-Lucas numbers, and call such numbers as the generalized Gauss k-Pell-Lucas numbers. We obtain relations between the family of the generalized Gauss k-Pell-Lucas numbers and the known Gauss Pell-Lucas ...

Convolutions of the generalized Pell and Pell-Lucas numbers

Filomat, 2016
We consider the convolution of the generalized Pell numbers-P(s) n,m and the convolution of the generalized Pell-Lucas numbers-Q(s) n,m. For s = 0, the sequence P(0) n,m represents the generalized Pell numbers Pn;m, and the sequence Q(0) n,m represents the generalized Pell-Lucas numbers Qn,m ([1], [2]). For m = 2 and s = 0, the numbers P(0)
