Title: SPLITTING THE REFERENCE TIME: TEMPORAL ANAPHORA AND QUANTIFICATION IN DRT.

Abstract: We present an analysis of temporal anaphora in sentences which contain quantification over events, within the framework of Discourse Representation Theory. The analysis in [12] of quantified sentences, introduced by a temporal connective, gives the wrong truth-conditions when the temporal connective in the subordinate clause is before or after. This problem has been previously analyzed in [19] as an instance of the proportion problem, and given a solution from a Generalized Quantifier approach. By using a careful distinction between the different notions of reference time, based on [16], we propose a solution to this problem, within the framework of DRT. We show some applications of this solution to additional temporal anaphora phenomena in quantified sentences.
