Title: Filters and sets of Vitali's type
Abstract. In construction of classical Vitali set on \(\{0,1\}^{\omega}\) we use filter of cofinite sets to define rational numbers. We replece cofinite filter by any nonprincipal filter on \(\omega\) and ask some questions about measurability and cardinality of selectors and equevalence classes.
