摘要:
本文研究通过Rayleigh-Ritz近似相应线性化问题的特征向量来估计非线性分支问题中的分岔系数。关键在于近似在足够强的范数下收敛,以使非线性项连续。利用Hilbert空间之间的二次插值来寻求分岔系数的尖锐收敛速率结果。给出了来自常微分和偏微分问题的例子。
英文摘要:
In this article we study the estimation of bifurcation coefficients in nonlinear branching problems by means of Rayleigh-Ritz approximation to the eigenvectors of the corresponding linearized problem. It is essential that the approximations converge in a norm of sufficient strength to render the nonlinearities continuous. Quadratic interpolation between Hilbert spaces is used to seek sharp rate of convergence results for bifurcation coefficients. Examples from ordinary and partial differential problems are presented.
