Unitary Triangularization of a Nonsymmetric Matrix [PDF]
Journal of the ACM, 1958 A method for the inversion of a nonsymmetric matrix, due to J. W. Givens, has been in use at Oak Ridge National Laboratory and has proved to be highly stable numerically but to require a rather large number of arithmetic operations, including a total of $n(n-1)/2$ square roots.

Calculation algorithm of rational estimations of recurrence periodical fourth order fraction
Karpatsʹkì Matematičnì Publìkacìï, 2014 Recurrence fourth order fractions are studied. Connection with algebraic fourth order equations is established. Calculation algorithms of rational contractions of such fractions are built.

A CHARACTERIZATION OF BAER-IDEALS [PDF]
Journal of Algebraic Systems, 2014 An ideal I of a ring R is called right Baer-ideal if there exists an idempotent e 2 R such that r(I) = eR. We know that R is quasi-Baer if every ideal of R is a right Baer-ideal, R is n-generalized right quasi-Baer if for each I E R the ideal In is right

Thirty-six full matrix forms of the Pascal triangle: Derivation and symmetry relations
Scientific African, 2021 For all 2≤n∈N, the four vertices (00),(n0),(2nn),(nn) of the Pascal Triangle expanded from level 0 to level 2n define the greatest embedded rhomboid sub-block denoted n−GRSB in this paper.

Matrix Games with Single-Valued Triangular Neutrosophic Numbers as Pay-offs [PDF]
Neutrosophic Sets and Systems, 2022 Game theory is commonly used in competitive situations because of its significance in decisionmaking. Different types of fuzzy sets can handle uncertainty in matrix games.

Functional identities on upper triangular matrix rings
Open Mathematics, 2020 Let R be a subset of a unital ring Q such that 0 ∈ R. Let us fix an element t ∈ Q. If R is a (t; d)-free subset of Q, then Tn(R) is a (t′; d)-free subset of Tn(Q), where t′ ∈ Tn(Q), tll′$\begin{array}{} t_{ll}' \end{array} $ = t, l = 1, 2, …, n, for any ...

A Class of Nonlinear Nonglobal Semi-Jordan Triple Derivable Mappings on Triangular Algebras
Journal of Mathematics, 2021 In this paper, we proved that each nonlinear nonglobal semi-Jordan triple derivable mapping on a 2-torsion free triangular algebra is an additive derivation.

Gorenstein-Projective Modules over Upper Triangular Matrix Artin Algebras
Journal of Mathematics, 2021 Gorenstein-projective module is an important research topic in relative homological algebra, representation theory of algebras, triangulated categories, and algebraic geometry (especially in singularity theory).
