Let \(V\subseteq \mathbb {A}^n\) be an affine variety, with \(\mathcal {I}_a(V)=(f_1,\ldots , f_m)\) and let \(P=(p_1,\ldots , p_n)\) be a point of V. Let r be a line passing through P, so that r has parametric equations of the form $$ x_i=p_i+\lambda _it, \quad \text {with}\quad t\in \mathbb {K}\quad \text {for}\quad i=1,\ldots , n,\quad \text ...

Linearization at a Singular Point
2000In this chapter we consider nonlinear control systems near a singular point, i.e., a common fixed point of the drift vector field and the control vector fields. Linearization at this point yields a bilinear system in ℝd; hence the linearized system is a special case of the general model considered in the preceding chapter.

How does a curve look in the neighborhood of a singular point? Recall that a formal definition of a singular and regular point on a curve (see Section 5.1) depends on a class of parametrization.

For a linear differential equation, a pole of the coefficient of the equation is called an irregular singular point if it is not a regular singular point. In this chapter, we explain the outline of the theory of irregular singular point. Several assertions are proved.
