The stabilized march technique is extended to nonlinear two-point boundary value problems via a new Generalized Brent Method for systems of nonlinear algebraic equations. The resulting algorithms can be used to solve systems of nonlinear rst-order ordinary diierential equations under partially separated nonlinear boundary conditions economically. Numerical(More)
The first half of life consists of the capacity to enjoy without the chance; the last half consists of the chance without the capacity. " We would like to thank the editor Thomas Schneeweis, two anonymous referees, Bernd Fitzenberger, Alexander Lembcke and Joachim Zietz for very helpful comments and suggestions on an earlier draft of this paper.

In this study, we transform the spring-mass model for running into a parametrized boundary value problem. We show that the new approach can be extended for investigations of the asymmetric spring-mass model. The new approach allows the computation of bifurcations and points on the event hyperplanes. Hence, the study of the region of the stable solutions can(More)
This paper analyses the short-and long-term relationships between hedge funds and traditional financial assets for the main emerging market regions of Asia, Latin America, and Eastern Europe by using multivariate cointegration analysis. Because cointegrated assets are tied together over the long term, a portfolio consisting of these assets lowers(More)
The purpose of this paper is to use He's variational iteration methodfor solving Bratu's boundary value problem, using only three terms in series expansion of nonlinear part. The method converges rapidly and approximates the exact solution very accurately. Two special cases of the problem are illustrated by using two iterates of the recursive scheme and the(More)
In this paper, we study the solution eld M of a class of nonlinear parametrized two-point boundary value problems. Typical representatives of this class are the shell equations of Bauer, Reiss, Keller 1] and Troger, Steindl 24]. The boundary value problems are formulated as an abstract operator equation T (x;) = 0 in appropriate Banach spaces of(More)
This paper analyzes market reactions triggered by announcements that hedge funds and private equity investors purchase large blocks of voting rights. We argue that changes in share-holders' wealth are related to the opportunity, possibility and motivation of being an active blockholder, who successfully reduces agency problems. The investigation is based on(More)
