Ambrose-Kakutani-Krengel-Kubo-theorem[edit]

Ambrose is also known for his representation of measure preserving ergodic flows as flows under a function. This was later extended to flows which need not be ergodic by Ambrose-Kakutani and to flows which are only nonsingular by Krengel and Kubo. This turned out to be important in the theory of operator algebras. It is discussed in the section "Ergodic Flows" of Wikipedia. In the Encyclopedia of Mathematics Prof. K. Ito wrote in 1993: "In this connection the theorem of Krengel and Kubo plays a significant role." Krengel achieved the representation of semiflows (which need not be invertable)and Daniel Rudolph showed that the ceiling function can be constructed with the property that it assumes only two values. --Golf-ulk (talk) 08:39, 20 January 2022 (UTC)[reply]

Incoherent sentence[edit]

The sentence

"For example, less than ten years after André Weil presented the differential form, Ambrose was using it in his undergraduate differential geometry courses."

makes no sense, since no reader has any idea what "the differential form" means here. 2601:200:C000:1A0:49C3:22C7:EEE8:74BB (talk) 17:32, 14 October 2022 (UTC)[reply]
