Efficient Computation of Singular Points
IMA Journal of Numerical Analysis, 1989The author tries to reduce the computational work which is necessary for the iterative construction of singular solutions of systems of nonlinear equations. He proposes variants of a Gauss-Newton-type procedure which is based on a representation of a Moore-Penrose pseudoinverse of a matrix of moderate size.

On the Singular Points in the Problem of Inversion
The Annals of Mathematics, 1932Nach der Uniformierungstheorie ist es möglich, eine beliebig gegebene Riemannsche Fläche \(G(x, y) = 0\) vom Geschlecht \(p\) in der Form \(x =\varphi(t)\), \(y = \psi(t)\) zu uniformisieren, wo \(\varphi(t)\), \(\psi(t)\) automorphe Funktionen einer Hauptkreisgruppe \(\Gamma\) bezeichnen. Dadurch erhält man für die \(p\) Normalintegrale \(u_\alpha\) \(

Singular Point, Organizing Center and Acupuncture Point
The American Journal of Chinese Medicine, 1989A hypothesis is proposed on the nature of acupuncture point and organizing center, the role of meridian system in growth regulation, and the mechanism of acupuncture. Both organizing centers and acupuncture points have low electric resistance.

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.
