Ε-quadratic form
MATHEMATICAL CONCEPT
E-quadratic form; Ε-quadratic forms; Ε-quadratic hyperbolic forms; Hyperbolic ε-quadratic forms; Quadratic refinement; Ε-quadratic refinement; Ε-symmetric form; Skew-quadratic form
In mathematics, specifically the theory of quadratic forms, an ε-quadratic form is a generalization of quadratic forms to skew-symmetric settings and to *-rings; , accordingly for symmetric or skew-symmetric. They are also called (-)^n-quadratic forms, particularly in the context of surgery theory.
