Ergodic Functions That are not Almost Periodic Plus $L^1-$Mean Zero
Jean Carlos Cardozo da Silva · arXiv (Cornell University) · 2020
Ergodic Functions are bounded uniformly continuous $(\text{BUC})$ functions that are typical realizations of continuous stationary ergodic process. A natural question is whether such functions are always the sum of an almost periodic with an $L^1-$mean zero $\text{BUC}$ function. The paper answers this question presenting a framework that can provide infinitely many ergodic functions that are not almost periodic plus $L^1-$ mean zero.
