Target class: theorem about eigenvalues
Context triple: [Weyl inequalities, instanceOf, theorem about eigenvalues]

• A. mathematical theorem
  A mathematical theorem is a rigorously proven statement derived from axioms and previously established results, expressing a fundamental truth within a formal mathematical system.
• B. existence and uniqueness theorem
  The existence and uniqueness theorem states that, under certain conditions on a differential equation and its initial values, there exists exactly one solution passing through a given point.
• C. equation in functional analysis
  An equation in functional analysis is a relation, typically involving functions and operators on infinite-dimensional spaces, that specifies conditions these objects must satisfy, often to study existence, uniqueness, and properties of solutions.
• D. result in linear algebra chosen
  In linear algebra, a result is a proven statement or conclusion—such as a theorem, lemma, or corollary—that follows logically from definitions and previously established facts about vectors, matrices, and linear transformations.
• E. theorem in metric number theory
  A theorem in metric number theory is a rigorous statement describing the behavior of number-theoretic objects (such as Diophantine approximations or distribution of sequences) for "almost all" real numbers with respect to a given measure, typically Lebesgue measure.
• F. None of above.
