Von Neumann spectral theory is applied to nonorthogonal cyclic subspaces, and the isometries onto C (N) are explicitly evaluated.en-USIn Copyrightcalculusoperator equationssubspacesArticle - Refereedhttp://scitation.aip.org/content/aip/journal/jmp/17/2/10.1063/1.522871https://doi.org/10.1063/1.522871
