WebIn matematica, una C*-algebra è un'algebra complessa di operatori lineari continui definiti su uno spazio di Hilbert complesso con due proprietà aggiuntive: . è un insieme (topologicamente) chiuso nella topologia della norma degli operatori. è chiuso rispetto all'operazione di prendere l'aggiunto di un operatore. L'interesse per le C*-algebre … WebC*-algebra formalism; Generalized statistical model of quantum mechanics; A related topic is the relationship to classical mechanics. Any new physical theory is supposed to reduce to successful old theories in some approximation. For quantum mechanics, this translates into the need to study the so-called classical limit of quantum mechanics ...

In the mathematical study of logic and the physical analysis of quantum foundations, quantum logic is a set of rules for manipulation of propositions inspired by the structure of quantum theory. The field takes as its starting point an observation of Garrett Birkhoff and John von Neumann, that the structure of … See more The most notable difference between quantum logic and classical logic is the failure of the propositional distributive law: p and (q or r) = (p and q) or (p and r), where the symbols p, q and r are propositional … See more The remainder of this article assumes the reader is familiar with the spectral theory of self-adjoint operators on a Hilbert space. However, the main ideas can be understood in the … See more Mackey observables Given a orthocomplemented lattice Q, a Mackey observable φ is a countably additive homomorphism from the orthocomplemented lattice of Borel subsets of R to Q. In symbols, this means that for any … See more In his classic 1932 treatise Mathematical Foundations of Quantum Mechanics, John von Neumann noted that projections on a Hilbert space can … See more Quantum logic can be axiomatized as the theory of propositions modulo the following identities: • See more The structure of Q immediately points to a difference with the partial order structure of a classical proposition system. In the classical case, … See more Quantum logic embeds into linear logic and the modal logic B. The orthocomplemented lattice of any set of quantum propositions can be embedded into a Boolean algebra, which is then amenable to classical logic. See more michael smerconish cnn show
