Target class: automorphic form
Context triple: [Siegel modular form, instanceOf, automorphic form]

• A. automorphic representation (in a broad sense)
  An automorphic representation (in a broad sense) is an irreducible unitary representation of an adelic or locally compact group that arises in the spectral decomposition of spaces of automorphic forms, encoding number-theoretic and geometric information via harmonic analysis on arithmetic quotients.
• B. endomorphism of modular forms space
  An endomorphism of a modular forms space is a linear self-map of a given space of modular forms (typically of fixed weight, level, and character) that sends each modular form in the space to another modular form in the same space.
• C. L-function
  An L-function is a complex analytic function, typically expressed as a Dirichlet series with an Euler product, that encodes deep arithmetic information about objects such as numbers, fields, or algebraic varieties.
• D. analytic function chosen
  An analytic function is a complex-valued function that is locally given by a convergent power series, meaning it is differentiable at every point in its domain and in a neighborhood around each point.
• E. meromorphic one-form
  A meromorphic one-form is a differential 1-form on a complex manifold that is holomorphic except at isolated points where it has poles.
• F. None of above.
