BCH-algebra; interval-valued fuzzy set
A BCH-algebra is a binary groupoid \(G\) with a fixed element \(0\) such that the axioms \(xx=0\), \((xy)z=(xz)y\), \(xy=yx=0\to x=y\) are satisfied.
A characterization of interval-valued fuzzy subalgebras of \(G\) is given and a method for constructing a new interval-valued fuzzy subalgebra from an old one is presented. The images and inverse images of such fuzzy subalgebras are studied too.
