- In mathematics, a
degenerate case is a
limiting case of a
class of

qualitatively different from (and
usually simpler than)...
- The most
important examples of
nondegenerate forms are
inner products and
symplectic forms.
Symmetric nondegenerate forms are
important generalizations...
-
injective (hence "
nondegenerate" in the
above sense) but not unimodular. For example, over the integers, the
pairing B(x, y) = 2xy is
nondegenerate but not unimodular...
- In mathematics, a real
interval is the set of all real
numbers lying between two
fixed endpoints with no "gaps". Each
endpoint is
either a real number...
- is a

metric tensor that is
everywhere nondegenerate. This is a
generalization of a
Riemannian manifold in
which the requirement...
-
spaces if they have an
inner product (or more
generally a
symmetric nondegenerate form) and an orientation; this is less data than an
isomorphism to Euclidean...
-
signature (p, 1), or (1, p).
There is
another notion of
signature of a
nondegenerate metric tensor given by a
single number s
defined as (v − p),
where v...

includes positive definite,
negative definite, and
