The importance of spectral flow for homotopy and index theory are discussed in detail. Applications concern eta-invariants, the Bott-Maslov and Conley-Zehnder indices, Sturm-Liouville oscillation theory, the spectral localizer and bifurcation theory UR - https://library.oapen.org/bitstream/id/7572019a-9110-4e53-9e13-ff5114dd6825/9783111172477.pdf UR - https://library.oapen.org/handle/20.500.12657/63798 ER -
