摘要: In this talk, we first solve four conjectures recently proposed by Heng and Ding (IEEE TIT, 68(6): 3643-3656, 2022). Besides, we also determine the weight distributions of subfield codes derived from $x^3$ and oval polynomials over $\F_{2^m}$. The second ingredient is to obtain two classes of p-ary linear codes from monomials over $\F_{p^m}$. We study the parameters of the constructed codes and determine their weight distributions. Notably, we show that the codes$\mathcal{C}_{(x^{p^i},p^m)}^{(p)}$ are optimal and almost optimal in many cases with respect to the online Database of Grassl. Finally, we observe that the derived linear codes also have the minimality property for most cases.
