WebbHe stated four primality-related theorems. The most famous of these, Proth"s theorem, can be used to test whether a Proth number (a number of the form k2n + 1 with k odd and k < 2n) is prime. The numbers passing this test are called Proth primes. They continue to be of importance in the computational search for large prime numbers. WebbIt was shown in 2024 that the reciprocal sum of Proth primes converges to a real number near 0.747392479, substantially less than the value of 1.093322456 for the reciprocal …

WebbFor p < 2n, one can use Proth’s Theorem to determine whether p2n +1 is prime. In this paper we extend a similar condition for k= pprime and no constraints on the relative sizes of 2n and p. For the rest of this paper, we will denote Ras R= p2n + 1, n>1. This bridges the gap between the Sophie-Germain Primality Test and Proth’s Theorem, for n>1 shore orthopaedic tinton falls nj

In number theory, Proth's theorem is a primality test for Proth numbers. It states that if p is a Proth number, of the form k2 + 1 with k odd and k < 2 , and if there exists an integer a for which $${\displaystyle a^{\frac {p-1}{2}}\equiv -1{\pmod {p}},}$$then p is prime. In this case p is called a Proth prime. This is a practical test … Visa mer Examples of the theorem include: • for p = 3 = 1(2 ) + 1, we have that 2 + 1 = 3 is divisible by 3, so 3 is prime. • for p = 5 = 1(2 ) + 1, we have that 3 + 1 = 10 is divisible by 5, so 5 is prime. Visa mer • Pépin's test (the special case k = 1, where one chooses a = 3) • Sierpinski number Visa mer The proof for this theorem uses the Pocklington-Lehmer primality test, and closely resembles the proof of Pépin's test.
