Partially Ordinal Sums and $P$-partitions [PDF]

open access: yesThe Electronic Journal of Combinatorics, 2012
We present a method of computing the generating function $f_P(\textbf{x})$ of $P$-partitions of a poset $P$. The idea is to introduce two kinds of transformations on posets and compute $f_P(\textbf{x})$ by recursively applying these transformations. As an application, we consider the partially ordinal sum $P_n$ of $n$ copies of a given poset, which ...

A Note on Congruences of Infinite Bounded Involution Lattices

open access: yesScientific Annals of Computer Science, 2021
We prove that an infinite (bounded) involution lattice and even pseudo-Kleene algebra can have any number of congruences between 2 and its number of elements or equalling its number of subsets, regardless of whether it has as many ideals as elements or ...

Ordinal Sums of De Morgan Triples

open access: yesTrends in Computational and Applied Mathematics, 2018
In this paper we consider the ordinal sum of the summands (a_i, b_i, T_i) ((a_i, b_i, S_i)), where (T_i)_{i\in I}$ $((S_i)_{i\in I}) are a family of t-(co)norms and $(]a_i, b_i[)_{i\in I}$ a family of nonempty, pairwise disjoint open subintervals of [0,1]

Generating Fuzzy Implications by Ordinal Sums [PDF]

open access: yesTatra Mountains Mathematical Publications, 2016
Abstract This paper deals with ordinal sums of fuzzy implications. Some of the known constructions are recalled and new ways of generating fuzzy implications from given ones are proposed. Sufficient properties of fuzzy implications as summands for obtaining a fuzzy implication as a result are presented.

Audiovisual Delay as a Novel Cue to Visual Distance. [PDF]

open access: yesPLoS ONE, 2015
For audiovisual sensory events, sound arrives with a delay relative to light that increases with event distance. It is unknown, however, whether humans can use these ubiquitous sound delays as an information source for distance computation.
