Notes on von Neumann Algebras
... Thus (ηn ) is Cauchy, its limit is in C and has distance d from ξ. Exercise 2.1.3. If φ ∈ H∗ (the Banach-space dual of H consisting of all continuous linear functionals from H to C), kerφ is a closed convex subset of H. Show how to choose a vector ξφ orthogonal to ker φ with φ(η) = hξφ , ηi and so t ...

While a proof might be thought of as an abstract object existing only in our minds, the fact is that mathematics advances only in so far as proofs are communicated. And writing remains the principal means of such communication. So to be a m ...

The expressive power in the title refers to, on the one hand, the recursion-theoretic complexity of the problem of kernel existence and, on the other hand, to the axiomatic strength of solvability of digraphs of various classes.
