Hamiltonian difference systemsJacobi's formulaPicone's identityIn this paper we consider discrete Sturm–Liouville eigenvalue problems of the form L(y) k:=∑ n μ=0(Δ) μ r μ(k)Δμy k+1μ=λy k+1for 0kNn with y 1n==y 0=y N+2n==y N+1=0, where N and n are integers ...
Finding the Sum and Difference of Two MatricesTo solve a problem like the one described for the soccer teams, we can use a matrix, which is a rectangular array of numbers. A row in a matrix is a set of numbers that are aligned horizontally. A column in a matrix is a set of ...
Szekeres used supplementary difference sets with one symmetry condition (a 鈭 M a M) to construct skew Hadamard matrices. He pointed out to Seidel that there was no skew Hadamard matrix of order 36 known (at that time). The chapter also discusses amicable cores of amicable Hadamard matrices...
(A, A *) or its cycle contains A2 or (A *)2 and if tr (A,A *)=tr(A * A) m/2 then A is a normal matrix; 2.If the difference of the numbers of A's and A* 's in the word is k≠0, then tr (A *) = tr(A * A)m/2 if and only if A k = (A *A) k/2....
Main results are analogs of the Minkowski, Bergstrom and Fan inequalities for the difference of two M-matrices.Let AB be M-matrices of order n. If AB is an inverse M-matrix, then and where A(i)B(i) denote the principal submatrices obtained by deleting the ith row and column, and ...

The sum matrix in the equation is the inverse A^{-1} of the difference matrix A. Example: The differences of x = (1, 2, 3) are b = (1, 1, 1). So b= Ax and x = A^{- 1}b: A \boldsymbol{x}=\left[\begin{array}{rrr} 1 & 0 & 0 \\ -1 & 1 & 0 \\ 0 & -...
