Why this reference is included
Morris’ Pontryagin Duality and the Structure of Locally Compact Abelian Groups (1977), published by Cambridge University Press, sits in the program’s reference corpus as a standing technical source. Cited in Book II (Categorical Holomorphy), Part 9, Chapter Boundary Characters via Idempotent Support, where the program draws on it in the context of “In classical Fourier analysis on a group G , a character χ : G → ℂ^× is a ``frequency detector’’ — it measures how much of a given frequency component is present in a signal.”
