设P(X)=PDX(D)+.。。+p(0)εZ[x]使得d大于或等于1,p(0)=1,p(0)大于或等于2,N={0,1,.。。,p(0)-1。本文证明了对{P(X),N}是典范数系的一个新判据。这使得我们能够证明:如果p(2),…,p(D)-1,Sigma(D)(I)=(1)p(1)大于或等于0,且p(0)>2Sigma(D)(I)=(1)\p(1),则{P(X),N}是标准数系。(C)2002 Elsevier Science B.V.保留所有权利。
Let P(X) = pdX(d) +. . . + p(0) epsilon Z[x] be such that d greater than or equal to 1, p(0)= 1, p(0) greater than or equal to 2 and N = {0,1, . . . ,p(0)-1. We are proving in this note a new criterion for the pair {P(x),N} to be a canonical number system. This enables us to prove that if p(2),..., p(d)-1, Sigma (d)(i)=(1) p(1) greater than or equal to 0 and p(0) > 2 Sigma (d)(i)=(1) \p(1)\, then {P(x),N} is a canonical number system.
