Trigonometric Series, Vol. I

Target entity: Trigonometric Series, Vol. I
Context triple: [Antoni Zygmund, notableWork, Trigonometric Series, Vol. I]

• A. Über die Darstellbarkeit einer Funktion durch eine trigonometrische Reihe
  Über die Darstellbarkeit einer Funktion durch eine trigonometrische Reihe is Bernhard Riemann’s seminal 1854 paper that laid foundational ideas for Fourier series and modern real analysis, including the concept now known as the Riemann integral.
• B. Dirichlet theorem on Fourier series
  The Dirichlet theorem on Fourier series gives conditions under which a periodic function can be represented by a convergent Fourier series, specifying how and where the series converges to the function.
• C. Lectures on Fourier Integrals
  Lectures on Fourier Integrals is a classic mathematical monograph by Salomon Bochner that systematically develops the theory and applications of Fourier integrals and transforms.
• D. Serie di Fourier e altre rappresentazioni analitiche delle funzioni di una variabile reale
  "Serie di Fourier e altre rappresentazioni analitiche delle funzioni di una variabile reale" is a classic mathematical treatise by Ulisse Dini on Fourier series and related analytic methods for representing real-valued functions.
• E. Theory of Multiply Periodic Functions
  Theory of Multiply Periodic Functions is a foundational mathematical work by Henry Frederick Baker that systematically develops the theory of functions with multiple complex periods, including abelian and related functions.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.
