两种形式的素数与挛生素数猜想

摘要

用模型论方法证明几乎一切形式为p^2＋4（p是素数）的数都是索数，几乎一切形式为2p＋l（P是素数）的数也都是素数．并证明关于各种素数的孪生素数猜想．%In this paper, il is proved by model-thenretic method thai nearly all numbers p2＋4（p is prime） are primes. Nearly all numbers of the form 2p ＋ l（p is a prime） are also primes. The twin-primes proved. conjecture for various kimls （d＂ primes is alsoproved
