Phrase: Lefschetz number | Statement: [Solomon Lefschetz, notableFor, Lefschetz number]

Target entity: Lefschetz number
Context triple: [Solomon Lefschetz, notableFor, Lefschetz number]

• A. Lefschetz number chosen
  The Lefschetz number is a topological invariant, computed from the traces of induced maps on homology, that predicts the existence and number of fixed points of a continuous self-map on a topological space.
• B. Lefschetz fixed-point theorem
  The Lefschetz fixed-point theorem is a fundamental result in algebraic topology that relates the number of fixed points of a continuous map on a topological space to traces of the induced maps on its homology groups.
• C. Lefschetz
  Lefschetz is a surname most notably associated with Solomon Lefschetz, a pioneering mathematician in algebraic topology and geometry.
• D. Lefschetz operator
  The Lefschetz operator is a linear operator in Kähler geometry that acts on differential forms by wedging with the Kähler form, playing a central role in the Hard Lefschetz theorem and Hodge theory.
• E. Poincaré–Hopf theorem
  The Poincaré–Hopf theorem is a fundamental result in differential topology that relates the sum of the indices of a vector field’s isolated zeros on a compact manifold to the manifold’s Euler characteristic.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
