Edge-of-the-wedge theorem (original) (raw)

About DBpedia

In mathematics, Bogoliubov's edge-of-the-wedge theorem implies that holomorphic functions on two "wedges" with an "edge" in common are analytic continuations of each other provided they both give the same continuous function on the edge. It is used in quantum field theory to construct the analytic continuation of Wightman functions. The formulation and the first proof of the theorem were presented by Nikolay Bogoliubov at the International Conference on Theoretical Physics, Seattle, USA (September, 1956) and also published in the book Problems in the Theory of Dispersion Relations. Further proofs and generalizations of the theorem were given by R. Jost and H. Lehmann (1957), F. Dyson (1958), H. Epstein (1960), and by other researchers.

(en) Теорема Боголюбова «об острие клина» утверждает, что функция нескольких комплексных переменных, голоморфная в двух клиновидных областях с общим острием, на котором она непрерывна, является голоморфной и на острие. Данная теорема используется в квантовой теории поля для построения аналитического продолжения . Первая формулировка и доказательство теоремы были приведены Н. Н. Боголюбовым на международной конференции в Сиэтле, США (сентябрь 1956 года) и также опубликованы в монографии (дополнение А, теорема 1). Впоследствии другие доказательства и обобщения теоремы были приведены Йостом и Леманом (1957), Дайсоном (1958), Эпштейном (1960) и другими математиками. Важными применениями теоремы об «острие клина» являются: доказательство дисперсионных соотношений в квантовой теории поля, аксиоматическая квантовая теория поля, теория обобщённых функций, обобщение теоремы Лиувилля.
