WebPositive-definiteness arises naturally in the theory of the Fourier transform; it can be seen directly that to be positive-definite it is sufficient for f to be the Fourier transform of a function g on the real line with g(y) ≥ 0.. The converse result is Bochner's theorem, stating that any continuous positive-definite function on the real line is the Fourier transform of a … WebApr 10, 2024 · 2024年3月31日-4月3日,数学科学学院成功举办“2024年安徽大学复分析学术研讨会”,会议开幕式由汪毅副院长主持并致欢迎辞,感谢各位专家帮忙之中来参加此次学术会议和长期以来对安徽大学复分析团队的关心和支持。随后,来自中国科学技术大学的任广斌教授作为复分析领域代表致辞,致辞中任 ...
