Pontryagin Duality and the Structure of Locally Compact Abelian Groups - Sidney A. Morris - Bog

These lecture notes begin with an introduction to topological groups and proceed to a proof of the important Pontryagin-van Kampen duality theorem and a detailed exposition of the structure of locally compact abelian groups. Measure theory and Banach algebra are entirely avoided and only a small amount of group theory and topology is required.
