n The paper deals with aggregation operators F :(5 ) → 5 which satisfy the classical require1 2 ments of binariness (independence), neutrality to alternatives, non-imposition, and which transform any n-tuple of individual relations of the given class 5 into a collective relation of the 1 given class 5 . We consider as 5 and 5 the classes: + of linear orders, 0 of weak orders, 6 2 1 2 of semiord...

With a view to study the convergence properties of the derivative expansion of the exact renormalization group (RG) equation, I explicitly study the leading and next-to-leading orders of this expansion applied to the Wilson-Polchinski equation in the case of the N-vector model with the symmetry O (N). As a test, the critical exponents η and ν as well as the subcritical exponent ω (and higher on...

fiqh (islamic jurisprudence) is known as the knowledge of life in islamic literature. so, political fiqh is usually defined as a go-between and coherent adaptor of faith and politics in islamic communities. in this article, i outline the general anatomy of political fiqh and attempt to provide a productive paradigm for understanding islamic society's politics. i concentrate in particular o...

We propose a method of using clustering techniques to partition a set of orders. We define the term order as a sequence of objects that are sorted according to some property, such as size, preference, or price. These orders are useful for, say, carrying out a sensory survey. We propose a method called the ko’means method, which is a modified version of a k-means method, adjusted to handle order...
