And the quantum bracket.

I will talk more about the classical bracket.

This is just an introduction.

And the quantum bracket or the operator is exactly the symmetrized operator XP uh x uh hat hat x hat p plus p hat x.

Okay?

So they do not coincide.

And indeed, you can't uh in indeed people have been trying to understand for which functions this works or not.

Here you have a little bit the proof of how you do the the commutator operator essentially.

We could do it as we did the the Heisenberg principle, or you could really just apply, expand it using this property of commutators.

Okay.

You say XP, sorry, can you say?

Exactly.

It's trickiness.

That's tricky.

That's a very good point.

So in a way, things that commute XP commutes because it's the product of functions, but not as operators, right?

And uh and then uh your question is very good.

So what do you have to do?

Then uh people have been looking a little bit more more about the cases that work and the cases that w that do not work.
