几乎正交可加函数
Almost orthogonally additive functions
摘要:
如果作用在欧几里得空间$f$上的函数$f$在$f(x+y)=f(x)+f(y)$对于所有$(x,y)\in\bot\setminus Z$的意义上是“几乎”正交可加的,其中$Z$是$(2n-1)$维流形$\bot\subset\mathbb{R}^{2n}$的“可忽略”子集,那么$f$几乎在几乎处处与某些正交可加映射重合。
英文摘要:
If a function $f$, acting on a Euclidean space $\mathbb{R}^n$, is "almost" orthogonally additive in the sense that $f(x+y)=f(x)+f(y)$ for all $(x,y)\in\bot\setminus Z$, where $Z$ is a "negligible" subset of the $(2n-1)$-dimensional manifold $\bot\subset\mathbb{R}^{2n}$, then $f$ coincides almost everywhere with some orthogonally additive mapping.
