Théories spectrales, chapter III, § 3. Endomorphismes de Fredholm et endomorphismes de Riesz
Let E be a separated locally convex space. Every Riesz endomorphism of E is of index zero.
This follows from the definition and lemma 2.
Bourbaki sets the proof directly after the statement, and the corpus does not separate them, so what is above is the statement and its proof together.
