• (lb, en, number theory) Mathematical theorem relating the Jacobi symbol $\backslash left(\{a\; \backslash over\; b\}\backslash right)$ to the inverted $\backslash left(\{b\; \backslash over\; a\}\backslash right)$, essentially relating the question of whether ''a'' is a square modulo ''b'' to the opposite question of whether ''b'' is a square modulo ''a'' (or modulo the prime factors).
