Some results on the weak dominance relation between ordered weighted averaging operators and T-norms
Aggregation operators have the important application in any fields where the fusion of information is processed. The dominance relation between two aggregation operators is linked to the fusion of fuzzy relations, indistinguishability operators and so on. In this paper, we deal with the weak dominance relation between two aggregation operators which is closely related with the dominance relation. Weak domination of isomorphic aggregation operators and ordinal sum of conjunctors is presented. More...

Stochastic fuzzy differential equations with an application
In this paper we present the existence and uniqueness of solutions to the stochastic fuzzy differential equations driven by Brownian motion. The continuous dependence on initial condition and stability properties are also established. As an example of application we use some stochastic fuzzy differential equation in a model of population dynamics.

Sufficient conditions for a T-partial order obtained from triangular norms to be a lattice
For a t-norm T on a bounded lattice , a partial order was recently defined and studied. In [11], it was pointed out that the binary relation is a partial order on , but may not be a lattice in general. In this paper, several sufficient conditions under which is a lattice are given, as an answer to an open problem posed by the authors of [11]. Furthermore, some examples of t-norms on such that is a lattice are presented.
Sum and product of the modified real fuzzy numbers
Sum of observables in fuzzy quantum spaces
We introduce the sum of observables in fuzzy quantum spaces which generalize the Kolmogorov probability space using the ideas of fuzzy set theory.
Synthesis of membership functions to determine a radius of influence.
In this work we study the synthesis of membership functions when they have been calculated from a set of observations according to the definition of (Zhang, 1993). The results obtained have been used to determine the radius of influence of a tramp for Podarcis lilfordi (a kind of saurians) in the island of Cabrera (Balearic Islands). The measure of this radius was used in a later work to estimate the density of these saurians in the island.

-equivalences generated by shape function on the real line
This paper is devoted to give a new method of generating T-equivalence using shape function and finding the exact calculation formulas of T-equivalence induced by shape function on the real line. Some illustrative examples are given.
-extension as a method of construction of a generalized aggregation operator
Generalized aggregation operators are the tool for aggregation of fuzzy sets. The apparatus was introduced by Takači in [11]. -extension is a construction method of a generalized aggregation operator and we study it in the paper. We observe the behavior of a -extension with respect to different order relations and we investigate properties of the construction.

-law of large numbers for fuzzy numbers
The notions of a -norm and of a fuzzy number are recalled. The law of large numbers for fuzzy numbers is defined. The fuzzy numbers, for which the law of large numbers holds, are investigated. The case when the law of large numbers is violated is studied.
The cancellation law for pseudo-convolution
Cancellation law for pseudo-convolutions based on triangular norms is discussed. In more details, the cases of extremal t-norms and , of continuous Archimedean t-norms, and of general continuous t-norms are investigated. Several examples are included.
The distribution of mathematical expectations of a randomized fuzzy variable.
The Shaffer's definition of the upper and lower expectations of fuzzy variables is considered with respect to randomized fuzzy sets. The notion of randomized fuzzy sets is introduced in order to evaluate fuzzy statistical indices for an arbitrary chosen fuzzy variable. Provided the distribution of the mathematical expectation of a randomized fuzzy variable is known, it is possible to adopt the traditional methods of testing statistical hypotheses for fuzzy variables.We show that this distribution...
