Abstract

This essay is an inquiry about the circumstances, and subsequent mathematical consequences, of the encounter, in 1955, of Maur\'icio M. Peixoto (1921 - 2019) with the work of Henry F. DeBaggis (1916 - 2002) on Structural Stability, Princeton 1952, developing a notion introduced by Alexander A. Andronov and Lev S. Pontrjagin, Gorkii 1937.
