Solomon Lefschetz - Wikipedia. Solomon Lefschetz (Russian: . He was educated there in engineering at the . He then took positions in University of Nebraska and University of Kansas, moving to Princeton University in 1. He remained there until 1.

In the application of topology to algebraic geometry, he followed the work of Charles . Torrent Snowflake Pro Software more. He proved theorems on the topology of hyperplane sections of algebraic varieties, which provide a basic inductive tool (these are now seen as allied to Morse theory, though a Lefschetz pencil of hyperplane sections is a more subtle system than a Morse function because hyperplanes intersect each other). The Picard–Lefschetz formula in the theory of vanishing cycles is a basic tool relating the degeneration of families of varieties with 'loss' of topology, to monodromy. His book L'analysis situs et la g. In 1. 92. 4 he was awarded the B.

Later, with the rise of cohomology theory in the 1. His work on topology was summed up in his monograph Algebraic Topology (1. From 1. 94. 4 he worked on differential equations. He was editor of the Annals of Mathematics from 1. During this time, Annals became an increasingly well- known and respected journal, and Lefschetz played an important role in this. Martin Company’s Research Institute for Advanced Studies (RIAS) in Baltimore, Maryland. His team became the world's largest group of mathematicians devoted to research in nonlinear differential equations.
