T-topologies on a lattice ordered group.
Montserrat Pons (1982)
Stochastica
Similarity:
In this paper a characterization of the topologies on a l-group arising from a CTRO (T-topologies) is given. We use it to find conditions under which the Redfield topology comes from a CTRO.
Some remarks on a problem of C. Alsina.
J. Matkowski, M. Sablik (1986)
Stochastica
Similarity:
Equation [1] f(x+y) + f (f(x)+f(y)) = f (f(x+f(y)) + f(f(x)+y)) has been proposed by C. Alsina in the class of continuous and decreasing involutions of (0,+∞). General solution of [1] is not known yet. Nevertheless we give solutions of the following equations which may be derived from [1]: [2] f(x+1) + f (f(x)+1) = 1, [3] f(2x) + f(2f(x)) = f(2f(x + f(x))). Equation [3] leads to a Cauchy functional equation: ...
Imprecise notions in individual and group decision theory: Resolutions of Allais paradox and related problems.
Hannu Nurmi (1982)
Stochastica
Similarity:
This paper deals with two ways in which uncertainty notions enter social science models: 1) They can be used in an effort to make intelligible some phenomena that would otherwise be difficult to comprehend, or 2) They can be use to generalize or modify the domain of validity of some theoretical results.
Wajsberg algebras.
Josep M. Font, Antonio J. Rodríguez, Antoni Torrens (1984)
Stochastica
Similarity:
We present the basic theory of the most natural algebraic counterpart of the ℵ-valued Lukasiewicz calculus, strictly logically formulated. After showing its lattice structure and its relation to C. C. Chang's MV-algebras we study the implicative filters and prove its equivalence to congruence relations. We present some properties of the variety of all Wajsberg algebras, among which there is a representation theorem. Finally we give some characterizations of linear, simple and semisimple...
Representation of continuous associative functions.
Barbara Baccheli (1986)
Stochastica
Similarity:
Strengthened forms of Ling's representation theorem concerning a class of continuous associative functions are given: Firstly the monotonicity condition is removed. Then the associativity condition is replaced by the power associativity.
Classification of the regular De Morgan algebras of fuzzy sets.
Francesc Esteva, Núria Piera (1984)
Stochastica
Similarity:
A characterization of regular lattices of fuzzy sets and their isomorphisms is given in Part I. A characterization of involutions on regular lattices of fuzzy sets and the isomorphisms of De Morgan algebras of fuzzy sets is given in Part II. Finally all classes of De Morgan algebras of fuzzy sets with respect to isomorphisms are completely described.
Weighted shift operators on l spaces.
Lucas Jódar (1986)
Stochastica
Similarity:
The analytic-spectral structure of the commutant of a weighted shift operator defined on a l space (1 ≤ p < ∞) is studied. The cases unilateral, bilateral and quasinilpotent are treated. We apply the results to study certain questions related to unicellularity, strictly cyclicity and the existence of hyperinvariant subspaces.
On the extension of Rosenbrock's theory in algebraic design on multivariable controllers.
Manuel de la Sen (1986)
Stochastica
Similarity:
System similarity and system strict equivalence concepts from Rosenbrock's theory on linear systems are used to establish algebraic conditions of model matching as well as an algebraic method for design of centralized compensators. The ideas seem to be extensible without difficulty to a class of decentralized control.
