Linear Matrix Inequality Approaches to Koopman Operator Approximation [PDF]

open access: green, 2021
The regression problem associated with finding a matrix approximation of the Koopman operator from data is considered. The regression problem is formulated as a convex optimization problem subject to linear matrix inequality (LMI) constraints. Doing so allows for additional LMI constraints to be incorporated into the regression problem.

Spectral radius of S-essential spectra

open access: yesМатематичні Студії, 2020
In this paper, we study the spectral radius of some S-essential spectra of a bounded linear operator defined on a Banach space. More precisely, via the concept of measure of noncompactness,we show that for any two bounded linear operators $T$ and $S ...

Estimates for Tsallis relative operator entropy [PDF]

open access: yes, 2017
We give the tight bounds of Tsallis relative operator entropy by using Hermite-Hadamard's inequality. Some reverse inequalities related to Young inequalities are also given.

Further Inequalities for the Weighted Numerical Radius of Operators

open access: yesMathematics, 2022
This paper deals with the so-called A-numerical radius associated with a positive (semi-definite) bounded linear operator A acting on a complex Hilbert space H. Several new inequalities involving this concept are established.

Unified treatment of fractional integral inequalities via linear functionals [PDF]

open access: yes, 2016
In the paper we prove several inequalities involving two isotonic linear functionals. We consider inequalities for functions with variable bounds, for Lipschitz and H\" older type functions etc.

Some generalizations of operator inequalities for positive linear maps

open access: yesJournal of Inequalities and Applications, 2016
In this paper, we generalize some operator inequalities for positive linear maps due to Lin (Stud. Math. 215:187-194, 2013) and Zhang (Banach J. Math. Anal. 9:166-172, 2015).
