Phrase: Poincaré duality theorem | Statement: [Hard Lefschetz theorem, isRelatedTo, Poincaré duality theorem]

Target entity: Poincaré duality theorem
Context triple: [Hard Lefschetz theorem, isRelatedTo, Poincaré duality theorem]

• A. Poincaré duality chosen
  Poincaré duality is a fundamental theorem in algebraic topology that relates the homology and cohomology groups of an oriented closed manifold in complementary dimensions.
• B. Lefschetz duality
  Lefschetz duality is a generalization of Poincaré duality that relates the homology of a compact manifold with boundary to the cohomology of the manifold relative to its boundary.
• C. 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.
• D. Pontryagin classes
  Pontryagin classes are characteristic classes associated with real vector bundles that capture topological information about the bundle’s curvature and play a central role in differential topology and geometry.
• E. 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.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
