WitrynaI will describe an extension of this problem which asks for similar results on the distribution of Hecke eigenvalues of GL(n) cusp forms in progressions modulo q. For GL(n) cusp forms with n ≤ 4, we can produce an exact analogue of the classical Bombieri-Vinogradov theorem, and we achieve nontrivial progress when n ≥ 5. WitrynaObserving that the order of a power divides that of the base, no power of 2 can be a primitive root of 17. ... is even. Let r be a primitive root modulo p. Observing r is reduced, it has an inverse ¯r modulo p. In fact, the identity rp−1 ≡ 1 mod p allows us to deduce r¯≡ rp−2 mod p. Observinggcd(p−1,p−2) = 1, we concludethat ¯r ...

So it seems that the density cannot be improved by much with current technology. (But Pappalardi did manage to prove $\mathrm{ord}_p^{\times}{a} … Witryna15 wrz 2024 · Solution 1. Another equivalent definition of a primitive root mod n is (from Wikipedia), a number g is a primitive root modulo n if every number coprime to n is congruent to a power of g modulo n. For example, 3 is a primitive root modulo 7, but not modulo 11, because. And you got all the possible results: 1, 3, 2, 6, 4, 5 . painted rooms with wood trim

WitrynaNote now that (x+1)^{t}-1 and (x+1)^{t}+1 are consecutive even numbers, so that they have gcd equal to 2 . Use modulo x to get (x+1)^{t}-1 \equiv 0(\bmod x) and (x+1)^{t}+1 \equiv 2(\bmod x), so that the first factor is a multiple of x, whereas the second one is of the form x q+2, with 2 being its only common factor with x.

"Witrynaorder of an element . In a group (a special set with an operation on it like addition or multiplication), elements have orders. Usually, on these pages, the group is the set of non-zero remainders modulo a prime and the order of a modulo p then is the least positive integer n such that a n ≡ 1 (mod p)..
