Abstract

The paper is concerned with the numerical stability of linear delay integro-differential 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 (ETR$_2$s), 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.
