Pointwise aggregation of maps: its structural functional equation and some applications to social choice theory
(Elsevier, 2017)
Artículo / Artikulua,
We study a structural functional equation that is directly related to the pointwise aggregation of a finite number of maps from a given nonempty set into another. First we establish links between pointwise aggregation and ...
Comparison meaningful operators and ordinal invariant preferences
(Elsevier, 2015)
Artículo / Artikulua,
The existence of a continuous and order-preserving real-valued function, for the class of continuous and ordinal invariant total preorders, defined on the Banach space of all bounded real-valued functions, which are in ...
Semicontinuous planar total preorders on non-separable metric spaces
(The Korean Mathematical Society, 2009)
info:eu-repo/semantics/article,
We prove that every non-separable connected metric space
can be endowed with a total preorder that is order-isomorphic to a nonrepresentable
subset of the lexicographic plane and semicontinuous with
respect to the metric topology.
On the structure of acyclic binary relations
(Springer, 2018)
Artículo / Artikulua,
We investigate the structure of acyclic binary relations from different points of view. On the one hand, given a nonempty set we study real-valued bivariate maps that satisfy suitable functional equations, in a way that ...
