On imaginable -fuzzy subalgebras and imaginable -fuzzy closed ideals in BCH-algebras.
Fuzzy BCI-subalgebras with interval-valued membership functions.
On fuzzy dot subalgebras of BCH-algebras.
On fuzzy topological subalgebras of BCC-algebras
We describe properties of subalgebras and BCC-ideals in BCC-algebras with a topology induced by a family of fuzzy sets.
Linear operators preserving maximal column ranks of nonbinary boolean matrices
The maximal column rank of an m by n matrix is the maximal number of the columns of A which are linearly independent. We compare the maximal column rank with rank of matrices over a nonbinary Boolean algebra. We also characterize the linear operators which preserve the maximal column ranks of matrices over nonbinary Boolean algebra.
