I agree with Aaron on this one.

What's wrong with Sum. The only issue I can see is that Sum represents some
kind of algebraic antidifference operator (see the discussion at
https://github.com/sympy/sympy/pull/1696 for example), whereas a series is
a mathematical summation. There are also subtle differences in the latter
if we con
I think that a lot of interesting objects in mathematics are representable
by some kind of series: power series, Fourier series (including orthogonal
bases other than complex exponentials), and series representations of
constants (e.g., many different ways of representing pi as a series).

Sorry for being unclear. I do share Aaron's opinion.

Just a heads up that I plan to completely rewrite the tutorial in the next
couple of weeks, so if you translate the current version, it will become
invalid.

I'm not sure he was suggesting to keep things separate. There is a lot of
stuff in the quantum module that is purely mathematical that *should* be
moved out into some separate submodule, and made to work with the other
parts of SymPy. The quantum module could then just subclass these things

So, algorithmically, what are our hopes of getting something like
sin(x)*exp(x) to work? Can a hyper/meijerg-based algorithm ever hope to
work? If we implement formulas for the nth derivative, and also the series
multiplication formula, what are the chances of a summation algorithm

For going this way, I implemented the rewrite(hyper) on some
of the newer special functions. But it's supported only on a
very few functions yet.

You're right, better keep things separate.
By the way, I added two new methods to my last commit to MultiArray in the
valued tensor PR: applyfunc and diff.
Besides, I'm currently pondering how to add "diff" capabilities to valued
tensors, see https://github.com/sympy/sympy/pull/2041#issuecommen

The `quantum` module reimplements a lot of stuff and it is in no way
connected to the tensor module, the diffgeom module, combinatorics,
matrix or any other module that is related to it in theory. If you
want them to work together you will have a lot of refactoring to do on
both sides.

I know this problem is related to the exponential map between lie algebras and
lie groups, do you have any reference on this issue?
By the way, I'm still pondering how to integrate quantum module's Operator with
