Hi folks - I have a couple of basic questions about fundamental(adsbygoogle = window.adsbygoogle || []).push({});

representations.

First of all, does every group have a set of fundamental

representations?

Secondly, I know that in the case of the (compact?) semi-simple groups, any other

representation of the group can be constructed by taking tensor

products of its L fundamental representations, where L is the group's

rank. Is this the case for all groups, or just the semi-simple ones?

Any help would be really appreciated. Thanks!
