String Corrected Spacetimes and SU(N)-Structure Manifolds

Using an effective field theory approach and the language of SU(N)-structures, we study higher derivative corrections to the supersymmetry constraints for compactifications of string or M-theory to Minkowski space. Our analysis is done entirely in the target space and is thus very general, and does not rely on theory-dependent details such as the amount of worldsheet supersymmetry. For manifolds of real dimension n<4 we show that the internal geometry remains flat and uncorrected. For n=4, 6, Kahler manifolds with SU(N)-holonomy can become corrected to SU(N)-structure, while preserving supersymmetry, once corrections are included.Comment: 27 page

Kaluza-Klein Theories Without Truncation

In this note we present a closed expression for the space-time effective action for all bosonic fields (massless and massive) obtained from the compactification of gravity or supergravity theories (such as type II or eleven-dimensional supergravities) from $D$ to $d$ space-time dimensions.Comment: 20 page

The syntactic structure of predicatives : clues from the omission of the copula in child english

This paper explores the syntax of main clause predicatives from the perspective of trying to account for an asymmetry in copular constructions in certain languages. One of the languages in which we find such an asymmetry is child English (around age 2). Specifically, new results show that children acquiring English tend to use an overt (and inflected) copula in individual-level predicatives, but they tend to omit the copula in stage-level predicatives. The analysis adopted to account for this pattern draws on evidence from adult English, Russian, Spanish and Portuguese that stage-level predicates are Aspectual (they contain AspP) while individual-level predicates are not (they involve only a lexical Small Clause predicate). Children's omission of the copula in structures with AspP is linked to the fact that at this stage of development, children fail to require finiteness in main clauses. In particular, Asp0 is temporally anchored in child English, thereby obviating the need for a finite (temporally anchored) Infl, i.e. an inflected copula
