I am reading Matej Bresar's book, "Introduction to Noncommutative Algebra" and am currently focussed on Chapter 1: Finite Dimensional Division Algebras ... ...
I need help with some remarks of Bresar on first Weyl Algebras ...
Bresar's remarks on Weyl Algebras are as follows:https://www.physicsforums.com/attachments/6236
View attachment 6237In the above text from Bresar we read the following: (see (1.4) above)
" ... ... It is straightforward to check that
$$[D, L] = I$$
the identity operator ..."Can someone please explain exactly why $$[D, L] = I$$ ... ... ?
(It looks more like $$[D, L] = 0$$ to me?)Help will be appreciated ...
