Especially Country Boy -- thank you for your tutorial and tolerance.

Yes, many mathematicians are rumored to do their best work before the age of 40, thus the Fields medal restriction. I will put to mind the hierarchy and definitions you posed about various sets.

Perhaps you should start a new thread and ask the question...

Each mathematical function can be expressed as a sum or serie ...
so you continue now by yourself

If you want to look at it that way. But not all such series will converge. You can only guarentee that you can write the series over a "small" interval.

This is true only for (complex) analytic functions which are a very small subset of all functions. "Most" functions (in the sense of Baire) aren't even differentiable, must less analytic and even smooth functions may fail to be analytic. I would go a different route with this one.
