EXPLICIT MINIMUM POLYNOMIAL, EIGENVECTOR, AND INVERSE FORMULA FOR NONSYMMETRIC ARROWHEAD MATRIX
, 2016 In this paper, we treat the eigenvalue problem for a nonsymmetric arrowhead matrix which is the general form of a symmetric arrowhead matrix. The purpose of this paper is to present explicit formula of determinant, inverse, minimum polynomial, and ...

On characteristic and permanent polynomials of a matrix
Special Matrices, 2017 There is a digraph corresponding to every square matrix over ℂ. We generate a recurrence relation using the Laplace expansion to calculate the characteristic and the permanent polynomials of a square matrix.

Maps on operators strongly preserving sharp order
, 2015 We discuss the structure of additive transformations on B(H) that are strongly monotone with respect to the -order and characterize them under the assumption of bijectivity.

On the arrowhead-Fibonacci numbers
Open Mathematics, 2016 In this paper, we define the arrowhead-Fibonacci numbers by using the arrowhead matrix of the characteristic polynomial of the k-step Fibonacci sequence and then we give some of their properties.

On Mann-type iteration method for a family of hemicontractive mappings in Hilbert spaces
, 2013 Let K be a compact convex subset of a real Hilbert space H and Ti:K→K, i=1,2,…,k, be a family of continuous hemicontractive mappings. Let αn,βni∈[0,1] be such that αn+∑i=1kβni=1 and satisfying {αn},βni⊂[δ,1−δ] for some δ∈(0,1), i=1,2,…,k.

An observation on the determinant of a Sylvester-Kac type matrix
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2020 Based on a less-known result, we prove a recent conjecture concerning the determinant of a certain Sylvester-Kac type matrix related to some Lie Algebras. The determinant of an extension of that matrix is presented.

Another formulation of the Wick’s theorem. Farewell, pairing?
Special Matrices, 2015 The algebraic formulation of Wick’s theorem that allows one to present the vacuum or thermal averages of the chronological product of an arbitrary number of field operators as a determinant (permanent) of the matrix is proposed.

Determinant evaluations for binary circulant matrices
Special Matrices, 2014 Determinant formulas for special binary circulant matrices are derived and a new open problemregarding the possible determinant values of these specific circulant matrices is stated. The ideas used forthe proofs can be utilized to obtain more determinant
