The eigenvalues of a tridiagonal matrix in biogeography [PDF]
In investigating a certain optimization problem in biogeography in [``Biogeography-based optimization'', IEEE Trans. Evol. Comput. 12, No. 6, 702--713 (2008)], \textit{D. Simon} encountered a certain tridiagonal matrix with a special structure, and made a conjecture regarding its eigenvalues.

The Explicit Inverse of a Tridiagonal Matrix [PDF]
The closed form inverse of a tridiagonal matrix, which is a slight generalization of a matrix considered by D. Kershaw ( Math. Comp. , v. 23, 1969, pp. 189–191), is given in this note. If the matrix has integer elements, an integer multiple of the inverse can be computed by integer arithmetic,

Fast triangularization of a symmetric tridiagonal matrix
A simple linear systolic array is presented for triangularizing a symmetric tridiagonal matrix by Gaussian Elimination using nearest neighbor pivoting. The array consists of three cells requiring an area bounded by four simple inner product cells. The design can compute the elimination in time 2n + k1 for the simple point case and using an implicit 2*2

The inverse of a tridiagonal matrix
The author obtains explicit formulae for the elements of the inverse of a general tridiagonal matrix by deriving the explicit solution of a second-order linear nonhomogeneous difference equation with variable coefficients, and then applying the solution to a boundary value problem with zero boundary values.

Eigenvalues of 2-tridiagonal Toeplitz matrix [PDF]
In this article an explicit formula for eigenvalues of a 2-tridiagonal Toeplitz matrix can be derived on the basis of a certain relation between the determinant of this matrix and the determinant of a pertinent tridiagonal matrix.

G-tridiagonal majorization on $\textbf {M}_{n,m}$
summary:For $X,Y\in \textbf {M}_{n,m}$, it is said that $X$ is \emph {g-tridiagonal} majorized by $Y$ (and it is denoted by $X\prec _{gt}Y$) if there exists a tridiagonal g-doubly stochastic matrix $A$ such that $X=AY$.
