diﬀerential equation is quite sedate, and its solutions easily understood. First, there are two equilibrium solutions: u(t) ≡ 0 and u(t) ≡ 1, obtained by setting the right hand side of the equation equal to zero. The ﬁrst represents a nonexistent populationwith noindividuals and hence no reproduction. The second equilibriumsolution 2019-09-12 · Comparing the Level of Stability between Standard (Single-Step) and Multi-Step Methods in Numerical Ordinary Differential Equations.

Nonlinear stability. For the standard system of ODEs, y ′ = f (t, y), a linear multistep method with k-steps would have the form:y n = − k j=1 α j y n−j + h k j=0 β j f n−j , (1)where α j , β j are constants, y n is the numerical solution at t = t n , and f n = f (t n , y n ).For the rest of this discussion, we will make the assumption that f is differentiable as many times as needed, and we will consider the scalar ODE y ′ = f (t, y) for simplicity in notation. Ordinary differential equation of order n ∈N: y(n) = f(t,y,y˙,,y(n−1)) . (8.1.12) Notation: superscript (n) =ˆ n-th temporal derivative t Gradinaru D-MA TH p. 442 8.1 Num. Meth.
