| Aug 11, 2023 at 2:22 | comment | added | Michael Hardy | $$ g_i = \sum_{j,k \mid j+k \equiv 0 \bmod n} f_j \cdot f_k$$ I wonder whether you meant $$ g_i = \sum_{j,k \mid j+k \equiv i \bmod n} f_j \cdot f_k \text{ ?}$$ As it is, the index $i$ appears on the left side and not on the right side. | |
