An unsteady linear lifting line method for the determination of the circulation and lift distribution along the span of a curved wing subject to harmonic small amplitude oscillations is presented. The method relies on the Pistolesi- Weissinger 3/4-ch

Here we discuss the stability and convergence of a quadrature method for Symm's integral equation on an open smooth arc. The method is an adaptation of an approach considered by Sloan and Burn for closed curves. Before applying the quadrature scheme,

A method which combines quadrature with trigonometric interpolation is proposed for singular integral equations on closed curves. For the case of the circle, the present method is shown to be equivalent to the trigonometric ?-collocation method toget

For Galerkin's method with finite elements as trial functions for strongly elliptic operator equations in the Hilbert scaleH t the super-approximation property and the optimal convergence rate are obtained by using the Aubin-Nitsche lemma. This appli

In this paper we propose an extension of Prandtl's lifting line theory to curved wings. The aim is to evidence the effect of the curved geometry on the aerodynamic efficiency. By means of an analytical-numerical integration methodology, leading asymp

SynopsisThe aim of this paper is the explicit canonical or standard factorisation of matrix functions with Wiener algebra elements. The present approach covers all regular 2 × 2 matrices where two entries are arbitrary and the remaining two are line

In this paper, an integral equation of the first kind with Riesz kernel is discussed. Since the kernel of this integral equation is analytic, this problem is severe ill-posed. We prove that, for solutions of the integral equation, a local conditional

In this note, we give a non-technical summary of our forthcoming paper [2]. After describing a class of collocation methods, we present two convergence theorems, and then discuss their implications for a model problem.
