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 admissible configurations…
[You fill in the rest, please!]

I shall expand on this bit a bit later on. Done, right today, within an hour.]
