متن کاملZ - Pencils
The matrix pencil (A,B) = {tB −A | t ∈ C} is considered under the assumptions that A is entrywise nonnegative and B−A is a nonsingular M-matrix. As t varies in [0, 1], the Zmatrices tB−A are partitioned into the sets Ls introduced by Fiedler and Markham. As no combinatorial structure of B is assumed here, this partition generalizes some of their work where B = I. Based on the union of the direc...

Liquid propylene oxide added to a variety of disinfectant solutions resulted in a significant reduction of the bacterial spore content of these solutions.
متن کاملClassifying Real Polynomial Pencils
Let RP be the space of all homogeneous polynomials of degree n in two variables with real coefficients. The standard discriminant Dn+1 ⊂ RP n is Whitney stratified according to the number and the multiplicities of multiple real zeros. A real polynomial pencil, that is, a line L ⊂ RP is called generic if it intersects Dn+1 transversally. Nongeneric pencils form the Grassmann discriminant D2,n+1 ...
متن کاملBalancing Regular Matrix Pencils
In this paper we present a new diagonal balancing technique for regular matrix pencils λB − A, which aims at reducing the sensitivity of the corresponding generalized eigenvalues. It is inspired from the balancing technique of a square matrix A and has a comparable complexity. Upon convergence, the diagonally scaled pencil has row and column norms that are balanced in a precise sense. We also s...
