Abstract
We investigate the arithmetical completeness theorems of some extensions of Fitting, Marek, and Truszczy\'{n}ski's pure logic of necessitation . For , let , which was introduced by Kurahashi and Sato, be the logic obtained from by adding the axiom scheme . In this paper, among other things, we prove that for each , the logic becomes a provability logic, that is, there exists a provability predicate of whose -verifiable modal principles are exactly the logic .
