....However, the focus has mostly been on giving a semantic representation for single sentences. Although some of the theories are couched in a dynamic setting (cf. for example [Bos95, Rey93] most of them do not give a formal account of the behavior of ambiguous expressions in a discourse, but see [Fer97, Mon98]. Roughly, two things are lacking: First, there is no detailed account of pronoun resolution. In [Bos95] coindexation is assumed and in UDRT ( Rey93, Rey95] only one way of binding is considered, but not different ways of binding in parallel. Second, there is no notion of an ambiguous context and ....

Examples such as Partee s above complicate extensions in the sense of Hodges [6] i.e. preserving previously defined equivalences) of logical (j Gamma )equivalence on Phi to E (assumed, for ....
