Die Zwischenbilanz: das erste StudienjahrLet us take a moment to remind ourselves of the definition of a surface given in the previous chapter (Definition?1.1). We introduce the terminology . to mean ..

https://doi.org/10.1007/978-3-662-43419-2We now take a small diversion to discuss some interesting properties of the projective plane and the Klein bottle that we introduced in the previous chapter. Recall that these are . that exist in their own right, without reference to an embedding space like ., but which nonetheless are locally homeomorphic to open sets in the plane.

Stefan Berger,Stefano Musso,Christian WickeWe have worked quite hard to find a space whose fundamental group?is non-trivial. We should capitalize on this result and see if we can find other, related spaces whose fundamental groups can now be computed easily as a result of our hard work. An example where this approach is successful is for ..

Surface Preliminaries,One of the main objects of study in this book is that of a surface. We will thus spend a good deal of time in the first two chapters explaining what a surface is.
