Title: Balanced Interval-Valued Fuzzy Graphs Authors: Rashmanlou, Hossein; Pal, Madhumangal Abstract: In this paper, we discuss notion of ring sum of product interval-valued fuzzy graphs. We define tensor product of two interval-valued fuzzy graphs and shown that the tensor product of two product interval-valued fuzzy graphs is a product interval-valued fuzzy graph. Likewise, given three independent theorems based on ring sum, join and isomorphism of product interval-valued fuzzy graphs. Finally, we define balanced and strictly balanced interval-valued fuzzy graphs and investigated several properties

Title: Multiple Regression of Fuzzy-Valued Variable Authors: Sarkar, Srabani; Pal, Madhumangal Abstract: In fuzzy domain, a variable (vague linguistic term) often depends not only on a single variable but on more then one variables. In such a situation multiple regression analysis is more appropriate than simple regression analysis involving one independent variable. This paper introduces fuzzy multiple regression equations of fuzzy sets those are treated as a variable with certain values assigned to them. The error analysis is done by using standard least square technique Description: 57-66

Title: Circulant Triangular Fuzzy Number Matrices Authors: Bhowmik, Monoranjan; Pal, Madhumangal; Pal, Anita Abstract: In this paper, we present some operations on circulant triangular fuzzy numbers matrices (TFNMs). The first row of the circulant matrices play important role in this study. We also study some properties of determinant and adjoint of circulant TFNMs. Finally, we investigate the distance of generalized TFNMs by a systematic process. Description: 141-154

Title: A Sequential Algorithm to Solve Next-to-Shortest Path Problem on Circular-arc Graphs Authors: Pal, Madhumangal; Mandal, Swagata Abstract: In this article, we study the problem of finding the next-to-shortest path in circular-arc graph. A next-to-shortest path between any pair of vertices in a shortest path amongst all paths between those vertices with length strictly greater than the length of the shortest path. The next-to-shortest path problem in a directed graph in NP-hard. Here we deigned a polynomial time algorithm to solve this problem for the circular-arc graph. Description: 201-217
