I learned a little about these concepts in a pure mathematical book.

I was thinking about their utility in physics.. I know they probably do.. What physical areas could these concepts be used in?

Ok, but it is not clear what you are talking about. Can you at least tell us which book?

An example of a group you've been given, and an invariant measure, and what a "sum over the group elements" entails, would be useful. Surely some example was given in your textbook. Surely they actually did a calculation when they introduced these things. So show us that calculation.
