Multiple Recurrences and the Associated Matrix Structures Stemming From Normal Matrices
There are many classical results in which orthogonal vectors stemming from Krylov subspaces are linked to short recurrence relations, e.g., three-terms recurrences for Hermitian and short rational recurrences for unitary matrices. These recurrence coefficients can be captured in a Hessenberg matrix, whose structure reflects the relation between the spectrum of the original matrix and the recurr...
متن کاملMatrices and Linear Recurrences in Finite Fields
Linear recurring sequences of order k are investigated using matrix techniques and some finite group theory. An identity, well-known when k = 2, is extended to general k and is used to study the restricted period of a linear recurring sequence over a finite field.
متن کاملOn the Hölder Continuity of Matrix Functions for Normal Matrices
In this note, we shall investigate the Hölder continuity of matrix functions applied to normal matrices provided that the underlying scalar function is Hölder continuous. Furthermore, a few examples will be given.
متن کاملSimultaneous modeling of multiple recurrences in breast cancer patients
Introduction: Breast cancer is one of the most common recurrence cancers among women. There are several factors that can affect multiple recurrence of this disease. On the other hand, simultaneous examination of the types of relapses will make the results more accurate. The purpose of this study was to use a joint frailty model to model multiple recurrences of breast cancer patients. Materials ...
متن کاملMatrices commuting with a given normal tropical matrix
Consider the space M n of square normal matrices X = (xij) over R ∪ {−∞}, i.e., −∞ ≤ xij ≤ 0 and xii = 0. Endow M n with the tropical sum ⊕ and multiplication ⊙. Fix a real matrix A ∈ M n and consider the set Ω(A) of matrices in M n which commute with A. We prove that Ω(A) is a finite union of alcoved polytopes; in particular, Ω(A) is a finite union of convex sets. The set Ω(A) of X such that A...
