I’m now writing a masters thesis in mathematics. I’d like to introduce basic definitions and theorems in the beginning. By basic I mean try basic, like the definition of a connected graph and the theorem about Eulerian paths (such a path exists if and only if even degrees).

The lecture notes written by my professor is really nice so I’d like to use his definitions (I’ll cite, of course). In this case can I cite his lecture notes?
