Triangular Matrix Representations
Journal of Algebra, 2000 A ring \(R\) is said to have a GTMR (reviewer's abbreviation for ``generalised triangular matrix representation'') if there is a positive integer \(n\) such that \(R\) is isomorphic to the ring of all \(n\times n\) upper triangular matrices with \(i\)-th diagonal entry in some ring \(R_i\) and with above-diagonal \((i,j)\)-entry in an \(R_i\)-\(R_j ...

Elementary triangular matrices and inverses of k-Hessenberg and triangular matrices
Special Matrices, 2015 We use elementary triangular matrices to obtain some factorization, multiplication, and inversion properties of triangular matrices. We also obtain explicit expressions for the inverses of strict k-Hessenberg matrices and banded matrices. Our results can

Relative Gorenstein Dimensions over Triangular Matrix Rings
Mathematics, 2021 Let A and B be rings, U a (B,A)-bimodule, and T=A0UB the triangular matrix ring. In this paper, several notions in relative Gorenstein algebra over a triangular matrix ring are investigated.

Static Scheduling Algorithm for Solving Sparse Matrixes on FPGA Architecture [PDF]
Jisuanji gongcheng, 2022 In power system simulations, the solution of large-scale sparse matrixes will consume a lot of storage and computing resources, and a failure to effectively utilize the sparsity of the matrix will lead to a waste of storage space and low computing ...

Weakly Gorenstein comodules over triangular matrix coalgebras
AIMS Mathematics, 2022 In this paper, we characterise weakly Gorenstein injective and weakly Gorenstein coflat comodules over triangular matrix coalgebras by introducing the class of weakly compatible bicomodules.

Tame triangular matrix algebras [PDF]
Colloquium Mathematicum, 2000 Let \(A\) be a finite dimensional \(k\)-algebra for \(k\) algebraically closed, such that the triangular matrix algebra \(T_2(A)\) is tame. It is known that in this case, \(A\) is of finite representation type and standard. In this paper, the authors describe, in terms of full, convex subcategories of \(\widetilde A\) (the universal Galois covering of \
