The lecture notes for course 421 (Algebraic topology), taught at Trinity College, Dublin, in the academic year 1998-1999, are available also here. (Note that the syllabus for the course as taught that year differs from the current syllabus.)
The course consisted of four parts:-
- Part I: Topological Spaces
- [DVI], [PDF], [PostScript]
- Part II: Covering Maps and the Fundamental Group
- [DVI], [PDF], [PostScript]
- Part III: Simplicial Homology Theory
- [DVI], [PDF], [PostScript]
- Part IV: The Topological Classification of Closed Surfaces
- [PostScript]
The lecture notes for part of course 421 (Algebraic topology), taught at Trinity College, Dublin, in Michaelmas Term 1988 are also available:
In 1988 the course included material on the construction of covering maps over locally simply-connected topological spaces. In particular, it was shown that, given any of subgroup of the fundamental group of a locally simply-connected topological space, one can construct a corresponding covering space whose fundamental group is isomorphic to that subgroup.
