Abstract
In this work, we consider a complete lattice L and we study L-fuzzy context sequences which
represent the evolution in time of an L-fuzzy context. To carry out this study, in the first part of
the paper, we consider n-ary OWA operators in complete lattices, which enable us to make a
general analysis and a temporal analysis at any moment in time of L-fuzzy context sequences.
After that, evolut ...

In this work, we consider a complete lattice L and we study L-fuzzy context sequences which
represent the evolution in time of an L-fuzzy context. To carry out this study, in the first part of
the paper, we consider n-ary OWA operators in complete lattices, which enable us to make a
general analysis and a temporal analysis at any moment in time of L-fuzzy context sequences.
After that, evolution in time of the relationship between the objects and the attributes is
considered. In particular, we analyze the concepts of Trend and Persistent formal contexts.
Finally, we illustrate our results with an example where we consider the particular lattice
L = J ([0, 1]). [--]
