Intuitionistic fuzzy signed graphs of the second type

Abstract

The aim of this paper is to introduce a new concept of intuitionistic fuzzy signed graph of second type as an extension of the intuitionistic fuzzy graph of second type defined by Sheik and Srinivasan (Sheik Dhavudh, S. and Srinivasan, R. (2017), Intuitionistic fuzzy graphs of second type, Advances in Fuzzy Mathematics, 12, 197--204; Sheik Dhavudh, S. and Srinivasan, R. (2017), A study on intuitionistic fuzzy graphs of second type, International Journal of Mathematical Archive, 8(8),  31--33; Sheik Dhavudh, S. and Srinivasan, R. (2017),  Properties of intuitionistic fuzzy graphs of second type, International Journal of Computational and Applied Mathematics, 12(3), 815--823) and the intuitionistic fuzzy signed graph defined by Mishra and Pal (Mishra, S.N.  and Pal, A. (2016), Intuitionistic fuzzy signed graphs, International Journal of Pure and Applied Mathematics,106 (6), 113--122). Also we establish some of its properties.
