Web12. apr 2024. · The values on the 1-line have much significance. For example, the fact that \zeta (1+\textrm {i} t)\ne 0 implies the prime number theorem. The extreme values of \zeta (1+\textrm {i} t) have been widely investigated. In 1925, Littlewood [ 10] showed that there exists arbitrarily large t for which. magic booster pack contents
