ABSTRACT = {
This paper explores the development of calculi using different proof
methods for propositional dynamic modal logics.
Dynamic modal logics are PDL-like extended modal logics which are
closely related to description logics.
We show how tableau systems, modal resolution systems and
Rasiowa-Sikorski systems, which are dual tableau systems, can be
developed and studied by using standard principles and methods of
first-order theorem proving.
We translate modal logic reasoning problems to first-order
clausal form and then use a suitable refinement of resolution to
construct and mimic derivations using the desired proof method.
The inference rules of the calculus can then be read off from the
clausal form used.
