Globalisierung und Weltpolitik,al again being the determination of canonical forms for the equivalence classes. In the case of negative discriminants, the “reduced” forms are essentially unique in a given equivalence class. For positive discriminants, however, it is not only the case that many reduced forms can lie in the same cl未成熟 发表于 2025-3-27 03:38:23

For class number 4, only the cyclic or Klein 4-groups are possible, and these can be distinguished by the number of ambiguous forms. Thus, the groups for discriminants −39, −55, −63, −155, −56, −68, and −80 are cyclic, while the groups of discriminants −84 and −96cortex 发表于 2025-3-27 09:54:25
