In this study, we introduce some systems of subsets of intuitionistic fuzzy
special sets (IFSS), namely, intuitionistic fuzzy special sigma-algebra (I
FS sigma-A), intuitionistic fuzzy special algebra, intuitionistic fuzzy spe
cial ring and intuitionistic fuzzy special Dynkin system. We also introduce
the concepts of intuitionistic fuzzy special measurability of IFSS, intuit
ionistic fuzzy special measures and intuitionistic fuzzy special measurable
functions. Finally, consequences of these concepts and some basic results
are given. (C) 2000 Elsevier Science Inc. All rights reserved.
