Comments on "$\alpha$ -Plane Representation for Type-2 Fuzzy Sets: Theory and Applications

This comment points out a misnomer and two errors in a previous paper by the author (
IEEE Trans. Fuzzy Syst.
, vol. 17, no. 5, pp. 1189-1207, Oct. 2009), and because one of the errors relates the term "α-plane" to the term "z-slice," it also connects these two terms more correctly.
