What is Diamond operator?

In mathematical analysis, Fourier integral operators have become an important tool in the theory of partial differential equations. The class of Fourier integral operators contains differential operators as well as...

In mathematics, more specifically in functional analysis, a positive linear operator from an preordered vector space...

In mathematical physics, the almost Mathieu operator arises in the study of the quantum Hall effect. It is given by acting as a self-adjoint operator on the Hilbert space...

In computer programming, scope is an enclosing context where values and expressions are associated. The scope resolution operator helps to identify and specify the context to which an identifier refers,...

In mathematics, in the area of functional analysis and operator theory, the Volterra operator, named after Vito Volterra, is a bounded linear operator on the space L of complex-valued square-integrable...

In operator theory, a bounded operator T: X → Y between normed vector spaces X and Y is said to be a contraction if its operator norm ||T || ≤ 1. This...

In operator theory, a bounded operator T on a Hilbert space is said to be nilpotent if T = 0 for some n. It is said to be quasinilpotent or...

Given a unital C*-algebra A...

In the C++ programming language, the move assignment operator = is used for transferring a temporary object to an existing object. The move assignment operator, like most C++ operators, can...
