Hi(adsbygoogle = window.adsbygoogle || []).push({});

I am trying to get a simple grasp of the concept of a group generator and group representations.

As ever wherever I look, I get very mathematical speak definitions such as:

"A representation is a mapping that takes elements g in G into linear operators F that preserve the composition rule".

I get the second half of the sentence but I still get stuck conceptually as soon as I read the words: 'a mapping that takes a group of elements into linear operators'

And similarly, I am stuck on the word 'generators.'

Thanks

Peter
