Nettetis called linearly degenerate if among the commuting PDEs (1.10)–(1.12) there exists at least one satisfying (1.13) along with the condition ∂λi(u) ∂ui = 0, i= 1,...,n. The motivation for our terminology is that one of the quasilinear systems of the commuting family (1.10)–(1.12) is linearly degenerate, i.e., the ith characteristic ... Nettettion.

A degenerate conic is a conic section (a second-degree plane curve, defined by a polynomial equation of degree two) that fails to be an irreducible curve. • A point is a degenerate circle, namely one with radius 0. • The line is a degenerate case of a parabola if the parabola resides on a tangent plane. In inversive geometry, a line is a degenerate case of a circle, with infinite radius.

Nettet28. aug. 2024 · 3. From a more mathematical point of view, we say there is degeneracy when the eigenspace corresponding to a given eigenvalue is bigger than one-dimensional. Suppose we have the eigenvalue equation. A ^ ψ n = a n ψ n. Here a n is the eigenvalue, and ψ n is the eigenfunction corresponding to this eigenvalue.
