Interval type-2 fuzzy sets (IT2 FS) play an important part in dealing with uncertain read more applications.However, how to measure the uncertainty of IT2 FS is still an open issue.The specific objective of this study is to present a new entropy named fuzzy belief entropy to solve the problem based on the relation among IT2 FS, belief structure, an
A set of fixed points in N-point gravitational lenses is studied in the paper.We use complex form of lens mapping to study fixed points.There are some merits of using a complex form over coordinate.In coordinate form gravitational lens is described by a system of two equations and in complex form is described by one equation.We transform complex eq
