Phrase: Ramanujan sums | Statement: [Dirichlet characters, relatedTo, Ramanujan sums]

Target entity: Ramanujan sums
Context triple: [Dirichlet characters, relatedTo, Ramanujan sums]

• A. Ramanujan’s sum chosen
  Ramanujan’s sum is a number-theoretic function introduced by Srinivasa Ramanujan, expressing certain periodic arithmetic functions as finite trigonometric sums over primitive roots of unity.
• B. Ramanujan summation
  Ramanujan summation is a technique in mathematical analysis that assigns finite values to certain divergent series in a way consistent with analytic continuation and other regularization methods.
• C. Ramanujan tau function
  The Ramanujan tau function is a multiplicative arithmetic function arising from the Fourier coefficients of a modular discriminant form, central to the study of modular forms and number theory.
• D. Ramanujan theta function
  The Ramanujan theta function is a special type of q-series introduced by Srinivasa Ramanujan that plays a central role in the theory of modular forms, partitions, and mock theta functions.
• E. Poisson summation formula
  The Poisson summation formula is a fundamental result in harmonic analysis that links sums of a function over the integers to sums of its Fourier transform, with deep applications in number theory, signal processing, and physics.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
