Galerkin method for Wiener-Hopf operators with piecewise continuous symbol

Integral Equations and Operator Theory, 2000
The Galerkin method is applied to Wiener-Hopf operators with piecewise continuous symbols. For this, an algebra of sequences is introduced, which contains the approximating sequences. The objective of this paper is to study the stability of these sequences using spline Galerkin methods for Wiener-Hopf operators.

Continuous interval-valued Pythagorean fuzzy aggregation operators for multiple attribute group decision making

Journal of Intelligent & Fuzzy Systems, 2019
The interval-valued Pythagorean fuzzy set (IVPFS), as a new generalization of Pythagorean fuzzy set, which can be used to model complex uncertainty in the real multiple attribute group decision making (MAGDM) problems. This paper aims to develop some new

Invertibility of Nonlinear Operators and Parameter Continuation Method

1998
The article considers the invertibility of nonlinear operators which map a metric space or a weak metric space into a Banach space. It is shown that a nonlinear operator close to the invertible nonlinear operator is invertible. The analogous result for an operator distant from invertible operator is proved by parameter continuation method.

Continuous Operation Methods of Static Scherbius Control Systems at Instantaneous Power Failure

IFAC Proceedings Volumes, 1977
Abstract The static Scherbius control system, widely used for speed control of large-capacity induction motors, is incapable of smooth continuous operation at instantaneous power failure lasting about 0.1 to 0.6 second, because it is then subject to (a) commutation failure of inverter due to a lack of commutation voltage or to (b) overcurrent based ...

Continuous Interior Penalty hp-Finite Element Methods for Transport Operators

2007
A continuous interior penalty hp-finite element method that penalizes the jump of the discrete solution across mesh interfaces is introduced. Error estimates are obtained for first-order and advection-dominated transport operators. The analysis relies on three technical results that are of independent interest: an hp-inverse trace inequality, a local ...
