The spectrum of two interesting stochastic matrices
Special Matrices, 2020 The spectrum of two interesting stochastic matrices appearing in an engineering paper is completely determined. As a result, an inequality conjectured in that paper, involving two second largest eigenvalues, is easily proved.

Infant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 5, Page 541-556, September 2024.Abstract An efficient, multidimensional instrument is needed to screen non‐optimal prenatal parental representations predictive of postnatal parenting behavior and child attachment. The present work aimed to revise and validate the Prenatal Caregiving Expectations Questionnaire—Revised (PCEQ‐R).

On rademacher's conjecture and a recurrence relation of euler [PDF]
, 2004 We consider a connection between Rademacher's conjectural partial fraction decomposition for the reciprocal of Dedekind's eta function and Euler's recurrence relation for the partition function.

On the Rank of Cyclic Latin Squares [PDF]
, 2007 Recently, Fang, Shiu and Pan [3] suggested a new way to generate uniform designs based on cyclic Latin squares. The new designs have better uniformity than some other known uniform designs.

On three-dimensional q-Riordan arrays
Demonstratio MathematicaIn this article, we define three-dimensional q-Riordan arrays and q-Riordan representations for these arrays. Also, we give four cases of infinite multiplication three-dimensional matrices of these arrays.

On some special Legendre sums of the form
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017 We prove that sums of the form with f(X), g(X) ∈ ℤ[X] can be explicitly computed whenever f and g are subject to some certain conditions which are defined in the paper.

Unit group of the ring of negacirculant matrices over finite commutative chain rings
Special MatricesCirculant matrices form an important class of matrices that have been continuously studied due to their nice algebraic structures and wide applications. In this study, we focus specifically on negacirculant matrices, which are known as extensions of the ...

Some Determinants Involving Incomplete Fubini Numbers
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 We study some properties of restricted and associated Fubini numbers. In particular, they have the natural extensions of the original Fubini numbers in the sense of determinants.

On Doubled and Quadrupled Fibonacci Type Sequences
Annales Mathematicae SilesianaeIn this paper we study a family of doubled and quadrupled Fibonacci type sequences obtained by distance generalization of Fibonacci sequence. In particular we obtain doubled Fibonacci sequence, doubled and quadrupled Padovan sequence and quadrupled ...
