**Update on 18th June 2017: **

See the update to the last post; I have added three more diagrams depicting the mathematical abstraction of the problem, and also added a sub-question by way of clarifying the problem a bit. Hopefully, the problem is clearer and also its connection to QM a bit more apparent, now.

Here I *partly* expand on the problem mentioned in my last post [^]. … Believe me, it will take *more* than one more post to properly expand on it.

The expansion of an expanding function refers to and therefore requires *simultaneous* expansions *of* the expansions in both the space and frequency domains.

The said expansions may be infinite [in procedure].

In the application of the calculus of variations to such a problem [i.e. like the one mentioned in the last post], the most important consideration is the very first part:

Among all the kinematically

admissibleconfigurations…

[You fill in the rest, please!]
