Phrase: Weyl groups | Statement: [Deligne–Lusztig theory, involves, Weyl groups]

Target entity: Weyl groups
Context triple: [Deligne–Lusztig theory, involves, Weyl groups]

• A. Weyl group chosen
  A Weyl group is a finite reflection group associated with a root system that encodes the symmetries of Lie algebras and Lie groups in representation theory and geometry.
• B. Chevalley groups
  Chevalley groups are a broad class of linear algebraic groups constructed over arbitrary fields that generalize classical Lie groups and play a central role in the classification of finite simple groups.
• C. Weyl vector
  The Weyl vector is a distinguished element in the weight space of a semisimple Lie algebra, defined as half the sum of all positive roots and playing a central role in representation theory and the Weyl character formula.
• D. Weyl character formula
  The Weyl character formula is a fundamental result in representation theory that gives an explicit expression for the characters of irreducible finite-dimensional representations of semisimple Lie algebras and Lie groups.
• E. Weyl dimension formula
  The Weyl dimension formula is a fundamental result in representation theory that gives an explicit product expression for the dimension of each finite-dimensional irreducible representation of a semisimple Lie algebra or compact Lie group in terms of its highest weight and the root system.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
