摘要

For an odd prime p, let q=p^m, and denote Tr_e ^m the trace function from F_q onto F_p^e, where e is a divisor of m. For a positive integer t and a∈F_p^e, let D_a={(x₁,x₂,…,x_t)∈F_q ^t∖{(0,0,…,0)}:Tr_e ^m(x₁+x₂+⋯+x_t)=a}, and define a p-ary linear code C_{D_a} as C_{D_a}={c(x₁,x₂,…,x_t):(x₁,x₂,…,x_t)∈F_q ^t}, where c(x₁,x₂,…,x_t)=(Tr₁ ^m(x₁d₁ ²+x₂d₂ ²+⋯+x_td_t ²))_{(d₁,d₂,…,d_t)∈D_a}. The complete weight enumerators of linear codes C_{D_a} will be presented for any divisor e of m and a∈F_p^e, and this new result generalizes that of both Ahn et al. (2017) and Yang et al. (2017).
