International Journal of Engineering and Information Systems (IJEAIS)   Year: 2019 | Volume: 3 | Issue: 10 | Page No.: 16-26 Case Study As Application of T-norm on BL-algebra Habeeb Kareem Abdullah, Ahmed AL-Adilee, Hawraa A. AL-Challabi Abstract: This paper is concerned with the study of t-norm, and demonstrating a conditionality notion via algebraic structures of BL-algebra. On the other hand, we present some relations that explain the relationships between t-norm on BL-algebra and the classical probability space. Also, we illustrate some examples as applications of our work.
