Volterra advanced P-P model: the predator-prey model in the 20th century.
自从20世纪20年代,P-P模型:捕食者-猎物模型被Volterra提出后,它就成功的解释生物界的一些现象,例如:物种个体迁移、竞争现象、捕食现象、利他主义对生态系统的影响等。
In this paper we have intended, among others to prove the following: Theorem 1 Let p=4n+1 be prime, and let g be a primitive root modulo p, then g~(λ_1),g~(λ_2),…,g~(λ_k),k=1/4φ(p-1),1=λ_1<λ_2<λ…,λ_k<(p-1)/4, (λ_i, p-1)=1 and (g~(λ_i))~(-1), p-g~(λ_i), p-(g~(λ_i))~-1, i=1,2,…,k are all primitive roots modulo p.
本文给出了求模p~α和2p~α的一个或全部原根的切实可行的办法,比经典求法简便很多,从而可节省大量的时间和精力。
