A ball of radius 1.

A transformation of the form A^'=UAU^(H), where U^(H) denotes the conjugate transpose.

Capable of taking on exactly one possible value.

A function of a single variable (e.g., f(x), g(z), theta(xi), etc.).

If A is true unless B, then not-B implies A, but B does not necessarily imply not-A.

Kepler's original name for the small stellated dodecahedron.

If s_x is the standard deviation of a set of samples x_i and x^_ their mean, then the variation coefficient is defined as V=(s_x)/(x^_).

The magnitude (length) of a vector x=(x_1,x_2,...,x_n) is given by |x|=sqrt(x_1^2+x_2^2+...+x_n^2).

If the first nonzero component of the vector difference A-B is >0, then A≻B. If the first nonzero component of A-B is <0, then A≺B.

Vector subtraction is the process of taking a vector difference, and is the inverse operation to vector addition.
