  • n. A closed subset of an algebra.


Sorry, no etymologies found.


  • Then a state is operationally separated with respect to T if T's application does not change the result of applying the state to any element of the other subalgebra: it is operationally separable with respect to T if it is operationally separated, either with respect to T, or with respect to some other operation T* that coincides with the action of T on the other subalgebra.

    Bell's Theorem

  • For set-free formulations which, like those considered here, strictly adhere to a standard first-order language with a denumerable supply of open formulas, the correct way of summarizing the algebraic strength of GEM is this: Any model of this theory is isomorphic to a Boolean subalgebra of a complete Boolean algebra with the zero element removed ” a subalgebra that is not necessarily complete if Zermelo-Frankel set theory with the axiom of choice is consistent.
