I am reading Matej Bresar's book, "Introduction to Noncommutative Algebra" and am currently focussed on Chapter 1: Finite Dimensional Division Algebras ... ...(adsbygoogle = window.adsbygoogle || []).push({});

I need help with some remarks of Bresar on first Weyl Algebras ...

Bresar's remarks on Weyl Algebras are as follows:

In 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/how ##[D, L] = I## ... ... ?

(It looks more like ##[D, L] = 0## to me???)

Help will be appreciated ...

Peter
