1. <unit> /micro/ prefix denoting division by 10^6, e.g. mu m
(micrometre, a millionth part of a metre). Sometimes written
as a 'u', the ASCII character nearest in appearance.
2. <mathematics> /myoo/ In the theory of functions, mu x . E
denotes the least value of x for which E = x, i.e. the least
fixed point of the function \ x . E. The recursive
function mu f . H f satisfies (and is defined by) the equation
mu f . H f = H (mu f . H f)
An alternative notation for the same function is
fix H = H (fix H)
See fixed point combinator.
3. <database> multiple value.
