Trivially, any upper bound for the least prime quadratic residue modulo p is also an upper bound for the least prime non-primitive root modulo q. I can't recall what's been proved about the latter problem assuming GRH (probably a power of log q ), but that will form a good conjectural upper bound.

Webuse something called a primitive root. Theorem 3.1 Let pbe a prime. Then there exists an integer g, called a primitive root, such that the order of gmodulo pequals p 1. This theorem can be quoted on a contest without proof. Its proof is one of the practice problems. The point of this theorem is that given a primitive root g, each nonzero ... WebThe others are 2i where i is relatively prime to (25) = 20. So the primitive roots are 2, 23, 27, 29, 211, 213, 217, and 219. Clear up mathematic questions; Get detailed step-by-step …
WebGenerators. A unit g ∈ Z n ∗ is called a generator or primitive root of Z n ∗ if for every a ∈ Z n ∗ we have g k = a for some integer k. In other words, if we start with g, and keep multiplying by g eventually we see every element. Example: 3 is a generator of Z 4 ∗ since 3 1 = 3, 3 2 = 1 are the units of Z 4 ∗.

Web7 jul. 2024 · We say that an integer a is a root of f(x) modulo m if f(a) ≡ 0(mod m). Notice that x ≡ 3(mod 11) is a root for f(x) = 2x2 + x + 1 since f(3) = 22 ≡ 0(mod 11). We now introduce Lagrange’s theorem for primes. This is modulo p, the fundamental theorem of algebra. This theorem will be an important tool to prove that every prime has a ...
