reciprocity laws from euler to eisenstein springe

to Gauss Euler’s Early Contributions Leonhard Euler, one of history’s most prolific mathematicians, laid foundational stones for reciprocity laws through his work on quadratic residues. In the mid-18th century, Euler investigated the properties of quadratic residues modulo prime
