Determinants of the RSFPLR Circulant Matrices with the Jacobsthal Numbers
, 2020 In this paper, we study a special type of circulant matrices involving the Jacobsthal and Jacobsthal-Lucas numbers. We mainly calculate the determinant of these matrices using inverse factorization of polynomials. 2010 Mathematics Subject Classification:

A trace bound for integer-diagonal positive semidefinite matrices
Special Matrices, 2020 We prove that an n-by-n complex positive semidefinite matrix of rank r whose graph is connected, whose diagonal entries are integers, and whose non-zero off-diagonal entries have modulus at least one, has trace at least n + r − 1.

W-MPD–N-DMP-solutions of constrained quaternion matrix equations
Special Matrices, 2023 The solvability of several new constrained quaternion matrix equations is investigated, and their unique solutions are presented in terms of the weighted MPD inverse and weighted DMP inverse of suitable matrices.

Determinants of Block Tridiagonal Matrices [PDF]
, 2008 An identity is proven that evaluates the determinant of a block tridiagonal matrix with (or without) corners as the determinant of the associated transfer matrix (or a submatrix of it).Comment: 8 pages, final form.

Altered plasma cytokines in dogs with atopic dermatitis
Veterinary Dermatology, Volume 33, Issue 2, Page 131-e38, April 2022., 2022 Background – Canine (Canis lupus familiaris) atopic dermatitis (AD) shares similar clinical signs to human AD. The abnormal immune response of AD is orchestrated by T lymphocytes, and may include variable involvement of cytokines, Regulatory T (Treg) cells, eosinophils, mast cells and other immune components.

Proof of some properties of transfer using noncommutative determinants [PDF]
, 2018 A transfer is a group homomorphism from a finite group to an abelian quotient group of a subgroup of the group. In this paper, we explain some of the properties of transfers by using noncommutative determinants.

Determinants and Inverses of Ppoeplitz and Ppankel matrices
Special Matrices, 2018 In this paper, we consider two kinds of special matrices, which are called Ppoeplitz matrix and Ppankel matrix. The idea of matrix transformation is used to compute the determinants and inverses of the Ppoeplitz matrix and the Ppankel matrix.

Determinants of some special matrices over commutative finite chain rings
Special Matrices, 2020 Circulant matrices over finite fields and over commutative finite chain rings have been of interest due to their nice algebraic structures and wide applications. In many cases, such matrices over rings have a closed connection with diagonal matrices over
