INCLUDED, INCLUDES,and POST take a predicate of eventualities and return a predicate of times.INCLUDES, <strong>for</strong> example, maps the set of eventualities <strong>in</strong> the extension of P ontothe set of times that <strong>in</strong>clude the runtime of an eventuality of which P holds.Note that here, <strong>in</strong> contrast to de Swart’s account, aspect rather than tense<strong>in</strong>troduces the existential quantifier that b<strong>in</strong>ds the eventuality variable. Thetopic time is rendered as a variable t that ends up free <strong>in</strong> the semantic composition.It gets its value from the assignment function which is assumed to befixed by the context. This is one of the static ways of render<strong>in</strong>g <strong>in</strong>tersententialanaphora (see footnote 1). Note that whereas <strong>in</strong> account of Kamp et al. theanaphoric feature of tense is captured <strong>in</strong> terms of an anaphoric reference po<strong>in</strong>t,<strong>in</strong> von Stechow et al. it’s the topic time (comparable to the location time of29 Paslawska and von Stechow (2003) adopt the same convention as I do <strong>in</strong> the presentwork by us<strong>in</strong>g e as a variable <strong>for</strong> eventualities and t <strong>for</strong> times. In Gerö and von Stechow(2003), on the other hand, e is a variable <strong>for</strong> both events and times (no dist<strong>in</strong>ction is madebetween states and times) and τ maps events and times to times (if e is a time, τ is theidentity mapp<strong>in</strong>g).
