Commutation Methods for Jacobi Operators

Journal of Differential Equations, 1996
The authors observe that a complete spectral characterization of both the single and double commutation methods in the difference operator context is lacking in the literature and there seem to be no treatment of general backgrounds. In the present paper, the authors attempt to fill these gaps and provide a complete spectral characterization of the ...

Pythagorean Fuzzy Einstein Hybrid Averaging Aggregation Operator and its Application to Multiple-Attribute Group Decision Making

Journal of Intelligent Systems, 2018
Pythagorean fuzzy set is one of the successful extensions of the intuitionistic fuzzy set for handling uncertainties in information. Under this environment, in this paper, we introduce the notion of Pythagorean fuzzy Einstein hybrid averaging (PFEHA ...

Numerical Feynman integrals with physically inspired interpolation: Faster convergence and significant reduction of computational cost

AIP Advances, 2012
One of the most successful methods for calculating reduced density operator dynamics in open quantum systems, that can give numerically exact results, uses Feynman integrals. However, when simulating the dynamics for a given amount of time, the number of

Maximum Principle-Preserving Computational Algorithm for the 3D High-Order Allen–Cahn Equation

Mathematics
We propose an unconditionally stable computational algorithm that preserves the maximum principle for the three-dimensional (3D) high-order Allen–Cahn (AC) equation.

Stochastic Approximations and Perturbations in Forward-Backward Splitting for Monotone Operators

, 2015
We investigate the asymptotic behavior of a stochastic version of the forward-backward splitting algorithm for finding a zero of the sum of a maximally monotone set-valued operator and a cocoercive operator in Hilbert spaces. Our general setting features

Two step inertial Tseng method for solving monotone variational inclusion problem

Results in Applied Mathematics
In this paper, we examine the monotone variational inclusion problem with a maximal monotone operator and a Lipschitz continuous monotone operator. We propose two different iterative algorithms for solving the monotone variational inclusion problem ...

Identification of logical reasoning system by network operator method

RUDN Journal of Engineering Research, 2010
The problem of logical control synthesis is considered. It is necessary to construct a logical function on the basis of truth table. The method of network operator was used to solve the problem.

Iterative operator-splitting method

, 2011
In this paper we describe an iterative operator-splitting method for bounded operators. The contribution is a novel iterative method, that can be applied as a splitting method for ordinary and partial differential equations. A simple relation between the number of iterative steps and the order of the splitting scheme, can made it as an alternative ...

K-SMPC: Koopman Operator-Based Stochastic Model Predictive Control for Enhanced Lateral Control of Autonomous Vehicles

IEEE Access
This paper proposes Koopman operator-based Stochastic Model Predictive Control (K-SMPC) for enhanced lateral control of autonomous vehicles. The Koopman operator is a linear map representing the nonlinear dynamics in an infinite-dimensional space.
