- Semantics of Presupposition Inducers
- 概要：
-
It is well-known that presupposition inducers can have different
categories, usually functional ones. This means that the relation of
presupposition can hold between expressions which are of
sub-sentential category. In this talk I It is well-known that
presupposition inducers can have different grammatical proppose to
account for such non-sentential origins of presuppositions by
suggesting that presupposition inducers have as denotations specific
elements of relativised functional algebras. Functional algebras are
denotational algebras whose elements are functions (denotations of
functional expressions of the same category as a given presupposition
inducer). Functional algebras are relativised if their unit element 1
has been changed to a (and correspondingly the complement has been
relativised to a). For instance, to take the simplest case, if B is
the algebra of all properties, H is the property of being a human then
B(H) is the algebra relativied by H, that is the set of all
propertiers included in H in which H is a new unit element and the
complement C(X) of X is equal to the intersection of X' with H. One
observes that in such algebras all elements and their complements are
included in H (« entail » H) and thus H can be considered as a
(lexical) presupposition of any element of B(H). By generalising this
step to any functional category (where the relativising element will
be a constant function) and adding some additional constraints
(atomicity of algebras) we can account for the different categorial
status of presupposition inducers. Various examples of presuppositions
will be discussed in this context and the way of obtaining sentential
presuppositions from non-sentential ones will be indicated.

- Remarks on Kratzer's "Ordering-Premise" Semantics of Modalities and Conditionals
- 概要：
-
In the formal semantics of natural language, Kratzer's (1981; 1991)
"ordering-premise" semantics, which is a possible world semantics but
has two types of premise sets:"modal bases" and "ordering sources," is
the standard theory of modalities and conditionals, whereas in formal
logic, Kripke semantics and selection-function semantics are the
standard semantics of modal logics and conditional logics,
respectively. The naive question about Kratzer's "ordering-premise"
semantics is why it requires two types of premise sets simultaneously.
I will review Kratzer's "ordering-premise" semantics and try to
propose a simpler alternate, "multi-modal premise" semantics.
