A note on my paper: “On symmetric matrices whose eigenvalues satisfy linear inequalities” [PDF]

open access: yesProceedings of the American Mathematical Society, 1968
The first part of the theorem of the above paper states that if ois a closed convex set in real X1 ... Xn-space which is invariant under permutations of coordinates, and if C(o-) denotes the set of real symmetric nXn matrices whose eigenvalues X1, X. form the coordinates of points in a, then C(o) is convex. I am obliged to Professor R. T.

Some remarks on comparison of predictors in seemingly unrelated linear mixed models [PDF]

open access: yes, 2022
summary:In this paper, we consider a comparison problem of predictors in the context of linear mixed models. In particular, we assume a set of $m$ different seemingly unrelated linear mixed models (SULMMs) allowing correlations among random vectors ...

Finding Bit-Based Division Property for Ciphers with Complex Linear Layers

open access: yesIACR Transactions on Symmetric Cryptology, 2020
The bit-based division property (BDP) is the most effective technique for finding integral characteristics of symmetric ciphers. Recently, automatic search tools have become one of the most popular approaches to evaluating the security of designs against

Resolution of Linear-quadratic Problems in a Discrete-continuous Format with External Actions

open access: yesИзвестия Иркутского государственного университета: Серия "Математика", 2023
Two linear-quadratic problems are considered on the set of piecewise-constant controls. The first problem contains a discrete perturbation on the right side of the controlled system and uncertain parameters in a quadratic functional with sign-indefinite ...

Static output-feedback stabilization of discrete-time Markovian jump linear systems: a system augmentation approach [PDF]

open access: yes, 2010
This paper studies the static output-feedback (SOF) stabilization problem for discrete-time Markovian jump systems from a novel perspective. The closed-loop system is represented in a system augmentation form, in which input and gain-output matrices are ...
