Question: Which man received the Henri Poincaré Prize in 1997, the Fields Medal in 1998, Vladimir Levenshtein or Maxim Kontsevich?
Sentence (from "Poincaré–Steklov operator"): When the partial differential equation is discretized, for example by finite elements or finite differences, the discretization of the Poincaré–Steklov operator is the Schur complement obtained by eliminating all degrees of freedom inside the domain.
Relevant evidence: No
