		In functional analysis (a branch of mathematics), a bounded linear operator is a linear transformation L between normed vector spaces X and Y for which the ratio of the norm of L(v) to that of v is bounded by the same number, over all non-zero vectors v in X.
		A bounded linear operator is not necessarily a bounded function; the latter would require that the norm of L(v) be bounded for all v.
		An operator is bounded if it takes every bounded set to a bounded set, and here is meant the more general condition of boundedness for sets in a topological vector space (TVS): a set is bounded if and only if it is absorbed by every neighborhood of 0.

		It's a Banach algebra by that theorem which bounds the L_1 norm of fg by the product of the L_1 norms* of f and g.
		And it's a B-algebra because the L_1 norm* of the complex conjugate of f equals that of f.

		Notice that the definition of a vector norm was tied to the algebraic operations for vectors.
		What this means is that given a vector norm, they built an operator norm with all of the desired properties including (5).
		Of course it must be shown that a this defines a matrix norm, which it does.

		Without damping, the fact that the acceleration operator (assuming a uniform density) is Hermitian leads to several important properties, such as that the standing wave patterns are orthogonal functions.
		The operator norm of a square matrix is an upper bound for the moduli of its eigenvalues, and thus also for its spectral radius.
		For normal matrices, the operator norm induced by the Euclidean norm is the largest moduli among its eigenvalues.

	Hexapedia - Operator theory (via CobWeb/3.1 planet03.csc.ncsu.edu) (Site not responding. Last check: 2007-10-10)
		Operator theory is the branch of functional analysis which deals with bounded linear operators and their properties.
		It can be split crudely into two branches, although there is considerable overlap and interplay between them.
		These extend the spectral theory, for bounded operators.
