In this paper, we consider the solution of tridiagonal quasi-Toeplitz linear systems. By
exploiting the special quasi-Toeplitz structure, we give a new decomposition form of the …

Let A be a tridiagonal Toeplitz matrix denoted by A= Tritoep (β, α, γ) A= Tritoep (β, α, γ). The
matrix A is said to be: strictly diagonally dominant if| α|>| β|+| γ|| α|>| β|+| γ|, weakly …
