Synopsis

Explore the math behind primes, residues, and reciprocity in this historical note on quartic and cubic residuacity. It introduces key ideas from early 20th‑century number theory, including how primes relate to residues and the role of Pepin’s formulas in practical calculations.


This selection outlines the structure of a memoir that studies four‑ and three‑power residuacity with respect to prime moduli. It explains how forms p = a^2 + b^2 arise, the use of complex factors, and how reduced congruences simplify computations. The notes blend historical context with method, showing how authors of the era approached explicit reciprocity and tabulated data to support number theory work.



  • Definitions and notation for bases and residues modulo primes

  • How quartic and cubic residuacity are defined and computed

  • The role of Pepin’s formulas and related tables

  • What reduced congruences look like and how they are applied


Ideal for readers of mathematical history, history of number theory, and practical computation in modular arithmetic.
