The notion of resonance is refined, and the notions of Se hela listan på scholarpedia.org This paper studies the link between the number of critical eigenvalues and the number of delays in certain classes of delay-differential equations. There are two main results.

A has complex eigenvalues λ1 = λ and λ2 = ¯λ with corresponding complex eigenvectors W1 = W and W 2 = W . The key observationis that if X(t) is a complex solution, split X in its real and imaginary parts,

The eigenvalues and the stability of a singular neutral differential system with single delay are considered. Firstly, by applying the matrix pencil and the linear operator methods, new algebraic criteria for the imaginary axis eigenvalue are derived.

We wish to obtain the eigenvalues and eigen-vectors of an ordinary differential equation or system of equations. The differential equation is replaced by a homogeneous system of difference equations [10]. so where we left off we I had given you the question you know it's these these these type of equations are fairly straightforward when we have two real roots then this is the general solution and if you have your initial conditions you can solve for C 1 and C 2 but the question I'm asking is what happens when you have two complex roots or essentially when you're trying to solve the A “Hermitian” operator with imaginary eigenvalues.
