报告题目：Uniform and high-order discretization schemes for Sturm–Liouville problems via Fer streamers
报告时间：2015年8月15日上午10：00
报告地点：理科楼407
报告摘要：The current talk concerns the uniform and high-order discretization of the novel geometric integration approach to the computation of Sturm–Liouville problems via Fer streamers, put forth in (Ramos and Iserles, 2014, Numerische Mathematik, DOI: 10.1007/s00211-014-0695-0). In particular, the discretization schemes are shown to enjoy large step sizes uniform over the entire eigenvalue range and tight error estimates uniform for every eigenvalue. They are made explicit for global orders 4,7,10. In addition, the present talk provides total error estimates that quantify the interplay between the truncation and the discretization in the approach by Fer streamers.
