Abstract
We compare the expressiveness of the fragments
of Halpern and Shoham’s interval logic (HS), i.e.,
of all interval logics with modal operators associated
with Allen’s relations between intervals in linear
orders. We establish a complete set of interdefinability
equations between these modal operators,
and thus obtain a complete classification of
the family of 212 fragments of HS with respect to
their expressiveness. Using that result and a computer
program, we have found that there are 1347
expressively different such interval logics over the
class of all linear orders.
