The Picard-Lefschetz Theory

  • S. Lefschetz
Part of the Applied Mathematical Sciences book series (AMS, volume 16)


This problem arose in the study, first undertaken by Émile Picard In the period 1880–1905, of the extension to algebraic surfaces of the classical Riemann theory. The more remarkable part of this work is that Picard carried it out with the scantiest aid of algebraic topology, since indeed that chapter of mathematics was entirely in its infancy.
