Abstract(s)
We propose a new class of multiple contraction operations — the
system of spheres-based multiple contractions — which are a generalization
of Grove’s system of spheres-based (singleton) contractions to the case of
contractions by (possibly non-singleton) sets of sentences. Furthermore, we
show that this new class of functions is a subclass of the class of the partial
meet multiple contractions.
