  • An algebraic approach to Wigners unitary-antiunitary theorem
    In this paper we offer a different approach to Wigner's theorem Namely, instead of working in H, we push the problem to a certain operator algebra over H and apply some well-known results from ring theory to obtain the desired conclusion
  • Wiener Algebra -- from Wolfram MathWorld
    The set W with the usual pointwise operations and with the norm ||f||=sum_(k=-infty)^infty|alpha_k| (2) is a commutative Banach algebra and is called the Wiener algebra There is an isometric isomorphism between l^1(Z) and W given by f->f^~, where

  • Wigner algebra in a unit circle and deformed coherent states
    Wigner algebra is an obvious modification of the boson algebra Indeed, it reduces to an ordinary boson algebra when Wigner parameter goes to zero It is well known that Wigner algebra is linked to two particle Calogero model [10–12] when Wigner parameter is related to the Calogero coupling constant Wigner Hamiltonian which comes from Wigner
  • Wigners theorem and its generalizations - ScienceDirect
    A Wigner type theorem in its Uhlhorn form is proved with a difference: the orthogonality relation is not between two lines of a vector space E but between a line of E and a line of its topological dual Wigner's theorem in its classical form is deduced from this general result
