The Generalized Modal Operator F pα , β over p - Intuitionistic Fuzzy Sets

In the present paper a generalization of the operator Fα,β de ned by Atanassov in [1] is considered. This operator is de ned over the class of p-intuitionistic fuzzy sets. Its properties are studied and a Theorem analogous to the results obtained in [4] is proved.

In this paper, we obtain an axiomatic characterization of Lowen's fuzzy compactness. KeywordsMathematics, fuzzy sets, Topology, Lowen's compactness, operators.

On fuzzy compact-open topology

The concept of fuzzy compact-open topology is introduced and some characterizations of this topology are discussed.

Compact representations of Kohn-Sham invariant subspaces.

We present a method to compute a hierarchical approximate representation of the solutions of the Kohn-Sham equations. The method is based on a recursive bisection algorithm and yields one-particle wave functions localized on subdomains of varying sizes. The accuracy of the representation is set a priori by specifying the highest acceptable error in 2-norm for any solution. Applications to large...
