Christiane Schiersmann,Heinz-Ulrich Thielntury mathematicians, aptly characterizes the subservient place algebra held within mathematics for centuries. It is difficult to conceive even the most ardent nineteenth century champion of algebra suggesting that “algebra is the foundation and tool of all mathematics,” as Emmy Noether would do in 1931 .PARA 发表于 2025-3-25 08:49:51
