Mersenne-prímek
A matematika megoldatlan problémája: Létezik-e végtelen sok Mersenne-prím? (A matematika további megoldatlan problémái)
|
A matematikában Mersenne-prímeknek nevezzük a kettő-hatványnál eggyel kisebb, azaz a 2n ‒ 1 alakban felírható prímszámokat, ahol n szintén prímszám. A nevüket Marin Mersenne (1588–1648) francia szerzetes, matematikus, fizikus után kapták.
Matematikai alapok
[szerkesztés]Például a 31 (prímszám) = 32 ‒ 1 = 25 ‒ 1, és 5 szintén prím, ezért a 31 egy Mersenne-prím; hasonlóan, 7 = 8 ‒ 1 = 23 ‒ 1. Másrészt 2047 = 2048 ‒ 1 = 211 ‒ 1, nem Mersenne-prím, mivel bár a 11 prímszám, a 2047 nem az (osztható 89-cel és 23-mal). 1952-től a legnagyobb ismert prímszám Mersenne-prím, kivéve az 1989–1992 közötti időszakot.[1]
A Mersenne-prím definíciójában a kikötés, hogy n szükségképpen prím, elhagyható, ugyanis minden összetett n esetén elemi módon felbontható:
Általánosabban, a Mersenne-számok (nem feltétlenül prímek, de lehetnek azok is) olyan természetes számok, amelyek eggyel kisebbek egy kettő-hatványnál, tehát Mn = 2n − 1. (A legtöbb forrás a Mersenne-számoknál is megköveteli, hogy az n prímszám legyen.)

- ↑ "The 27th Mersenne prime. It has 13395 digits and equals 244497 – 1. [...] Its primeness was determined on April 8, 1979 using the Lucas–Lehmer test. The test was programmed on a CRAY-1 computer by David Slowinski & Harry Nelson." (p. 15) "The result was that after applying the Lucas–Lehmer test to about a thousand numbers, the code determined, on Sunday, April 8th, that 244497 − 1 is, in fact, the 27th Mersenne prime." (p. 17), David Slowinski, "Searching for the 27th Mersenne Prime", Cray Channels, vol. 4, no. 1, (1982), pp. 15–17.

- ↑ "This week, two computer experts found the 31st Mersenne prime. But to their surprise, the newly discovered prime number falls between two previously known Mersenne primes. It occurs when p = 110,503, making it the third-largest Mersenne prime known." I.
