The aim of the present paper is to completely characterize boundedness and compactness a sum operator defined by some more complex products composition, multiplication, mth iterated radial derivative operators from Bloch-type spaces weighted-type on unit ball. In applications, all ball are also characterized.

We introduce a new aggregation operator called the heavy ordered weighted averaging – weighted averaging (HOWAWA) operator. It is a new aggregation operator that uses the weighted average and the ordered weighted average in the same formulation and considering the degree of importance that each concept has in the analysis. Moreover, by using heavy aggregations, we are allowing the weighting vec...

We develop the fuzzy generalized ordered weighted averaging distance (FGOWAD) operator. It is a new aggregation operator that uses the main characteristics of the generalized OWA (GOWA), the ordered weighted averaging distance (OWAD) and uncertain information represented as fuzzy numbers. This operator includes a wide range of distance measures and aggregation operators such as the fuzzy maximu...

In this paper, we consider weighted composition operators betweenmeasurable differential forms and then some classic properties of these operators are characterized.

We compare the rate of decay singular numbers a given composition operator acting on various Hilbert spaces analytic functions unit disk D. show that for Hardy and Bergman spaces, our results are sharp. also give lower upper estimates with symbol “cusp map” lens maps, weighted Dirichlet spaces.

In this paper, the necessary and sufficient conditions for product of composition operators to be isometry are obtained on weighted Bergman space. With help a counter example we also proved that unlike [Formula: see text] operator induced by an analytic self-map with fixed origin need not norm one. We have generalized Schwartz’s [Composition text], thesis, University Toledo (1969)] well-known r...

This paper proposes a new approach based on Bonferroni mean operator and possibility degree to solve fuzzy multi-attribute decision making (FMADM) problems in which the attribute value takes the form of interval type-2 fuzzy numbers. We introduce the concepts of interval possibility mean value and present a new method for calculating the possibility degree of two interval trapezoidal type-2 fuz...

The aim of this paper is to model the processes of the aggregation of weighted information in a linguistic framework. Three aggregation operators of weighted linguistic information are presented: linguistic weighted disjunction (LWD) operator, linguistic weighted conjunction (LWC) operator and linguistic weighted averaging (LWA) operator. A study of their axiomatic is presented to demonstrate t...
