Number graph and essential self-adjointness

In particular,

The closed operator agrees on $\mathrm{Dom}(N)$ with the number-graph extension, by core approximation and closedness. The switched bilinear and the retarded coefficient have the same common-core action and hence the same closure.

The remainder satisfies

No numerical constant calculated from an unswitched observable is transferred without controlling these differences.

Figure fig:switched-remainder separates the exact switched identity from the controlled comparison with the unswitched fixed-time response.
