Operator theory
Topic: Category
From HandWiki - Reading time: 2 min
Here is a list of articles in the Operator theory category of the Computing portal that unifies foundations of mathematics and computations using computers. 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.
