Operator Theory on Symmetrized Bidisc [PDF]

, 2014
A commuting pair of operators (S, P) on a Hilbert space H is said to be a Gamma-contraction if the symmetrized bidisc is a spectral set of the tuple (S, P).

Vehicular Applications of Koopman Operator Theory—A Survey [PDF]

IEEE Access, 2023
Koopman operator theory has proven to be a promising approach to nonlinear system identification and global linearization. For nearly a century, there had been no efficient means of calculating the Koopman operator for applied engineering purposes.

Data-Driven Control of Soft Robots Using Koopman Operator Theory

IEEE Transactions on robotics, 2021
Controlling soft robots with precision is a challenge due to the difficulty of constructing models that are amenable to model-based control design techniques.

Approximation of functions by a class of Durrmeyer–Stancu type operators which includes Euler’s beta function

Advances in Difference Equations, 2021
In this work, we construct the genuine Durrmeyer–Stancu type operators depending on parameter α in [ 0 , 1 ] $[0,1]$ as well as ρ > 0 $\rho >0$ and study some useful basic properties of the operators.

Dunkl-type generalization of the second kind beta operators via ( p , q ) $(p,q)$ -calculus

Journal of Inequalities and Applications, 2021
The main purpose of this research article is to construct a Dunkl extension of ( p , q ) $(p,q)$ -variant of Szász–Beta operators of the second kind by applying a new parameter.

Nonlinear System Identification of Soft Robot Dynamics Using Koopman Operator Theory [PDF]

IEEE International Conference on Robotics and Automation, 2018
Soft robots are challenging to model due in large part to the nonlinear properties of soft materials. Fortunately, this softness makes it possible to safely observe their behavior under random control inputs, making them amenable to large-scale data ...

Existence of Solutions for Nonlinear Integral Equations in Tempered Sequence Spaces via Generalized Darbo-Type Theorem

Journal of Function Spaces, 2022
Two concepts—one of Darbo-type theorem and the other of Banach sequence spaces—play a very important and active role in ongoing research on existence problems.

Operator Theory on One-Sided Quaternionic Linear Spaces: Intrinsic S-Functional Calculus and Spectral Operators [PDF]

Memoirs of the American Mathematical Society, 2018
Two themes drive this article: identifying the structure necessary to formulate quaternionic operator theory and revealing the relation between complex and quaternionic operator theory.
