N-Fuzzy D-Subalgebras of D-Algebras
In this paper, we introduce the notion of fuzzy d-subalgebra of a d-algebra with respect to a triangular norm.
Then we show that the Cartesian product of two fuzzy d-subalgebras of d-algebra X with respect to a triangular norm is a
fuzzy d-subalgebra of the product of X with respect to the norm.
