Proof theory for indexed nested sequents
Abstract
Fitting's indexed nested sequents can be used to give deduc-tive systems to modal logics which cannot be captured by pure nested sequents. In this paper we show how the standard cut-elimination procedure for nested sequents can be extended to indexed nested sequents, and we discuss how indexed nested sequents can be used for intuitionistic modal logics.
