Abstract
The notions of regular uni-soft filters, uni-soft MV-filters and Boolean uni-soft filters are introduced, and related properties are investigated. Characterizations of regular uni-soft filters, uni-soft MV-filters and Boolean uni-soft filters are discussed.Relations between regular uni-soft filters and uni-soft MV-filters are considered. It is shown that the notion of a uni-soft MV-filter coincides with the notion of a regular uni-soft filter in BL-algebras.
