Cardinal characteristics associated with small subsets of reals

Inspired by Bartoszy\'nski's work on small sets, we introduce a new ideal defined by interval partitions on natural numbers and summable sequences of positive reals. Similarly, we present another ideal that relies on Bartoszy\'nski's and Shelah's characterization of F_ measure zero sets. We demonstrate that they are -ideals and provide characterizations of the families of all small sets and the ideal induced by F_ measure zero sets. We also study the cardinal characteristics associated with the introduced ideals. We discuss their connection to Cicho\'n's diagram and present related consistency results.
