Easy papers on fundamental groups (for beginners)

Question

I'd like to read some papers concerning fundamental groups, for example, papers written to explain some basic facts about homotopy explicitly for undergraduate students.

All the papers I have requires many background knowledge (homology, for example) but I'd a paper for young students.

I know that there are many good books but usually in books we find the theory explained in a row, or in the order just to read and follow. I'd like to start some research on a low level .

Suggestions are welcome. Best wishes.

Answer 1

There are many books in Algebraic Topology that discuss the fundamental group without talking about homology (singular/cellular or simplicial). Resources I have used:

1. Hatcher - Algebraic Topology (used in last semester's MATH 4204 at ANU)
2. Bredon - Geometry and Topology
3. Rotman - Algebraic Topology

There is no doing research without going through the basics and slogging it out in understandinh the full theory first.
