Wu, Chinese mathematician (Shanghai 12 May 1919 - Beijing 07 May 2017) ACHIEVEMENTS Discovered Wu classes and Wu formulas (1950) Introduced the notion of imbedding classes Introduced immersion and isotopic classes Discovered Adem-Wu relations (1952) independently Discovered a general constructive method of with non-homotopic topological invariants of polyhedra (1953) Gave a criterion for the planarity of linear graphs in
the form of solvability of some system of linear equations on mod 2
coefficients Gave methods of actually imbedding an imbeddable
graphs in the plane Discovered a simple computational method of defining
generalized Chern classes and Chern numbers of an algebraic variety with
arbitrary singularities via composite Grassmannians (1965) Established a method for solving algebraic and
differential equations by transforming an equation system in the general form
to equation systems in triangular form known as Ritt-Wu zero decomposition
theorem Established formulae to express Stiefel-Whitney class
by Wu classes and the relations among them Gave a new criterion for imbedding of a planner
diagram Suggested Cartan’s formula With Jiahe
Jiang introduced the concept of essential equilibrium of games (1962) Eponym of Wu method of characteristic set (1977) and Wu method
for solving multivariate polynomial equations (1970s)
