...However, the continuum problem itself, i.e., what aleph number the cardinality of the continuum truly is, remains unsolved today, and the main interest is in strengthening ZFC by searching for axioms that reflect the truth more accurately, such as those proposed by Martin D. Martin, and by researching various concepts of large cardinality. From [Class Field Theory]...This includes various reciprocity laws and is called the general reciprocity law. After that, C. Chevalley (1909-), J. Herbrand (1908-32), H. Hasse and others simplified the proof and made it arithmetical, and Tadashi Nakayama (1912-64), Artin and JT Tate (1925- ) and others applied cohomology theory, making it a theory with a wealth of content.

…しかし,連続体問題そのもの,すなわち,連続体の濃度は真にいかなるアレフ数であるか,は今日なお未解決であって,マルティンD.Martinの公理の提唱など,より真実を反映する公理の模索や種々の巨大濃度なる概念の研究などZFCの補強に主たる関心がはらわれている。 【類体論】より…これは種々の相互法則を含むものであり,一般相互法則と呼ばれている。その後も,シュバレーC.Chevalley(1909‐ ),エルブランJ.Herbrand(1908‐32),H.ハッセらによる証明の簡易化や算術化,中山正(1912‐64),アルティン,テートJ.T.Tate(1925‐ )らによるコホモロジー論の応用などにより,豊富な内容を含む理論となった。【斎藤 裕】。… ※「Herbrand,J.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
