第131期（2013年第14期）“海大青年学术沙龙”由数学系举办，沙龙的议题为“Delay-dependent Stability Analysis of Symmetric Boundary Value Methods for Linear Delay Integro-differential quations”。
本次邀请哈尔滨工业大学数学系赵景军教授作客大连海事大学青年学术沙龙，请他为广大年轻教师讲解积微分方程的稳定性等问题。
Abstract
The paper is concerned with the numerical stability of linear delay integrodifferential equations (DIDEs) with real coefficients. Four families of symmetric boundary value method (BVM) schemes, namely the Extended Trapezoidal Rules of first kind (ETRs) and second kind (ETR2s), the Top Order Methods (TOMs) and the B-spline linear multistep methods (BS methods) are considered in this paper.We analyze the delay-dependent stability region of symmetric BVMs by using the boundary locus technique. Furthermore, we prove that under suitable conditions the symmetric schemes preserve the delay-dependent stability of the test equation. Numerical experiments are given to confirm the theoretical results.
欢迎感兴趣的各专业学科的老师、学生参加探讨。
