William Schumacher Massey (August 23, 1920 [1] – June 17, 2017) was an American mathematician, known for his work in algebraic topology. The Massey product is named for him. He worked also on the formulation of spectral sequences by means of exact couples , and wrote several textbooks, including A Basic Course in Algebraic Topology ( ISBN 0 ...
His research interests lay in the area of algebra, involving abelian groups, modules, homological algebra, and combinatorics. [5] Rotman was the Managing Editor of the Proceedings of the American Mathematical Society in 1972–1973. [4] In 1985 he was the Annual Visiting Lecturer of the South African Mathematical Society. [6]
Algebraic topology is a branch of mathematics that uses tools from abstract algebra to study topological spaces. The basic goal is to find algebraic invariants that classify topological spaces up to homeomorphism, though usually most classify up to homotopy equivalence. Although algebraic topology primarily uses algebra to study topological ...
