Infimum
the infimum (plural infima) of a subset S of a partially ordered set T is the greatest element of T that is less than or equal to all elements of S. Consequently the term greatest lower bound (abbreviated as GLB) is also commonly used.

Normal Linear Operator
A linear operator “A” is called normal if it commutes with its adjoint: AA^+ = A^+A
Hermitian Linear Operator
A linear operator “H” is called hermitian if it is equal to its adjoint: H^+ = H
Unitary Linear Operator
A linear operator “U” is called unitary if it is inverse to its adjoint: UU^+ = I

Identifiability
An unknown parameter is “identifiable” if it can be determined uniquely in all points of its domain by using the input-output relation of the system and the input-output data.
