Antiunitary — In mathematics, an antiunitary transformation, is a bijective function:U:H 1 o H 2,between two complex Hilbert spaces such that :langle Ux, Uy angle = overline{langle x, y angle}=langle y, x angle for all x and y in H 1, where the horizontal bar… … Wikipedia

Unitary operator — For unitarity in physics, see unitarity (physics). In functional analysis, a branch of mathematics, a unitary operator (not to be confused with a unity operator) is a bounded linear operator U : H → H on a Hilbert space H… … Wikipedia
Unitary transformation — Informally, a unitary transformation is a transformation that respects the dot product: the dot product of two vectors before the transformation is equal to their dot product after the transformation. More precisely, a unitary transformation is… … Wikipedia
