Molodtsov’s soft set theory provides a general mathematical framework for dealing with uncertainty. The concepts of -SI implicative (Boolean) filters of BL-algebras are introduced. Some good examples are explored. The relationships between -SI filters and -SI implicative filters are discussed. Some properties of -SI implicative (Boolean) filters are investigated. In particular, we show that -SI implicative filters and -SI Boolean filters are equivalent.
