We prove some 3-adic congruences for binomial sums,which were conjectured by Zhi-Wei Sun.For example,for any integer m≡1(mod 3)and any positive integer n,we have v3(1/n ∑n-1X k=0 1/mk 2k/ k〉))≥min{3(n),3(...We prove some 3-adic congruences for binomial sums,which were conjectured by Zhi-Wei Sun.For example,for any integer m≡1(mod 3)and any positive integer n,we have v3(1/n ∑n-1X k=0 1/mk 2k/ k〉))≥min{3(n),3(m-1)-1},where 3(n)denotes the 3-adic order of n.In our proofs,we use several auxiliary combinatorial identities and a series converging to 0 over the 3-adic field.展开更多
