Solomon Lefschetz was a Russian born, Jewish mathematician who was the main source of the algebraic aspects of topology. His father Alexander Lefschetz and his mother Vera were both Turkish citizens but since Alexander Lefschetz worked as an importer he was required to travel a great deal.
In mathematics, the Lefschetz fixed-point theorem is a formula that counts the fixed points of a continuous mapping from a compact topological space to itself by means of traces of the induced mappings on the homology groups of . It is named after Solomon Lefschetz, who first stated it in 1926.
Solomon Lefschetz [3] used his idea of a Lefschetz pencil to prove the theorem. Rather than considering the hyperplane section alone, he put it into a family of hyperplane sections , where . Because a generic hyperplane section is smooth, all but a finite number of are smooth varieties.
