A note on polar decomposition based Geršgorin-type sets
Abstract: Let B ∈ Cn×n denote a finite-dimensional square complex matrix. In [6] and [7], Professor Varga and I introduced Geršgorin-type sets which were developed from Singular Value Decompositions (SVDs) of B. In this note, our work is extended by introducing the polar SV-Geršgorin set, Γ(B). The set Γ(B) is a union of n closed discs in C, whose centers and radii are defined in terms of the e...
متن کاملA Note on Iwasawa-Type Decomposition
In Poisson geometry, the groups SU p, q andAN the upper-triangular subgroup of SL n, with real positive diagonal entries are naturally dual to each other 1 . Therefore, it is important to know the geometry of the orbits of the dressing action. We show that the right dressing action of SU p, q is globally defined on the open subset of the so-called admissible elements of AN see Section 2 . We al...
متن کاملAn algorithm for computing minimal Geršgorin sets
The first algorithms for computing the minimal Geršgorn set were developed by Varga et all. in [17] for the use on small and medium size (dense) matrices. Here, we first discuss the existing methods and present a new approach based on the modified Newton’s method to find zeros of the parameter dependent left-most eigenvalue of a Z-matrix. Additionally, sampling technique used in the original wo...
متن کاملA note on order-type homogeneous point sets
Let OTd(n) be the smallest integer N such that every N -element point sequence in R d in general position contains an order-type homogeneous subset of size n, where a set is order-type homogeneous if all (d + 1)-tuples from this set have the same orientation. It is known that a point sequence in R that is order-type homogeneous, forms the vertex set of a convex polytope that is combinatorially ...
متن کاملA note on the Young type inequalities
In this paper, we present some refinements of the famous Young type inequality. As application of our result, we obtain some matrix inequalities for the Hilbert-Schmidt norm and the trace norm. The results obtained in this paper can be viewed as refinement of the derived results by H. Kai [Young type inequalities for matrices, J. Ea...
