对于大素数$$p$$p,{mathbb F}_p(X)$$ψ∈FP(X)中的有理函数$$psi,以及整数$$u$$u和$$hge 1$$H≥1,得到了数个连续值$$psi(X)$$ψ(X),$$x=u+1,ldots,u+H$x=u+1,…,u+H属于$${mathbb F}_p^*$$Fp∗的给定乘子群。
For a large prime $$p$$p, a rational function $$psi in {mathbb F}_p(X)$$ψ∈Fp(X) over the finite field $${mathbb F}_p$$Fp of $$p$$p elements, and integers $$u$$u and $$Hge 1$$H≥1, we obtain a lower bound on the number consecutive values $$psi (x)$$ψ(x), $$x = u+1, ldots , u+H$$x=u+1,…,u+H that belong to a given multiplicative subgroup of $${mathbb F}_p^*$$Fp∗.
