The technique of imaging was first introduced by Lewis (1976), in order to provide a novel account of the probability of conditional propositions. In the intervening years, imaging has been the object of significant interest in both AI and philosophy, and has come to be seen as a philosophically important approach to probabilistic updating and belief revision. In this paper, we consider the pos...

Using the twistor correspondence, we give a classification of toric anti-self-dual Einstein metrics: each such metric is essentially determined by an odd holomorphic function. This explains how the Einstein metrics fit into the classification of general toric anti-self-dual metrics given in an earlier paper [7]. The results complement the work of Calderbank–Pedersen [6], who describe where the ...

It has long been known that differential forms on a complex manifold M2n can be decomposed under the action of the complex structure to give the Dolbeault complex. This paper presents an analogous double complex for a quaternionic manifold M4n using the fact that its cotangent space T ∗ mM is isomorphic to the quaternionic vector space H. This defines an action of the group Sp(1) of unit quater...

American novelist and playwright Thornton Wilder’s lifelong attraction to passion for if not obsession with the work of James Joyce has led unintended consequences. Wilder was writing what would become his second Pulitzer Prize winning play, The Skin Our Teeth, while in midst “unriddling” Joyce’s final novel, Finnegans Wake. Accusations plagiarism subsequently arise from two major scholars, Jos...

IntroductIon Rulers of successful highland Mesoamerican cities, such as Teotihuacan and Monte Albán, had good reason for establishing and maintaining ties with coastal Oaxacan communities during the prehispanic era. The climatological and ecological regime of coastal Oaxaca made it a highly valuable and politically important region throughout prehispanic and early Colonial Mesoamerica. The raw ...
