摘要
本文给出当m=P_1P_2…P_r,P_1,P_2,…,P_r为素数,P_i≠P_j(1≤i≠j≤r)时,所有适合条件的整数e,以及这种整数的数目和应用。
This paper gives all the integers e, which satisfy the conditions e~≡e(modm), 0≤e<m, where m = P_1P_2… P_r, P_1 ,P_2, …,P_r are primes, P_i≠P_j, (1≤i≠j≤r). The number of the integers e and their application are also be given.
