Abstract
It is shown that, for any infinite set \(M\subset\mathbb N\) of density zero, there exists a rigid measure-preserving transformation of a probability space which is mixing along \(M\). As examples, Gaussian actions and Poisson suspensions over infinite rank-one constructions are considered. Analogues of the obtained result for group actions and a method not using Gaussian and Poisson suspensions are also discussed.
