8831Computing center conditions for non-analytic ninth degree vector fields with constant angular speed
http://library.wolfram.com/infocenter/Articles/9133/
Contributed by: Qingjun Ren, Yikun Huang, Feng Li. We investigate the planar ninth degree non-analytic Poincare systems which have center-focus equilibriums at the origins. Those systems could be changed into analytic systems by two transformations with the help of computer algebra system MATHEMATICA. The conditions of uniform isochronous center are obtained. Furthermore, we prove that five limit ...ArticlesTue, 27 Jan 2015 17:27:14 -0600Efficient optimal eighth-order derivative-free methods for nonlinear equations
http://library.wolfram.com/infocenter/Articles/9132/
Contributed by: Fazlollah Soleymani. This paper opens the issue of solving a nonlinear equation by iterative methods in which no derivative is required per iteration. Hence, an optimal class of three-step methods without memory is demonstrated, where each of its elements (methods) requires only four function evaluations per iteration to achieve the eighth order of convergence. In order to verify ...ArticlesTue, 27 Jan 2015 17:25:27 -0600Adomian Decomposition Method for Computing Eigen-Values of Singular Sturm-Liouville Problems
