Johan van Benthem Information Transfer in Chu Spaces Looking at properties of Chu Spaces as investigated by Vaughan Pratt, and viewing these spaces as two-sorted models, we'll determine which first-order statements are preserved under the natural Chu-transforms. In addition we discuss more general transfer of first-order statements along natural operations on Chu Spaces. If time permits, we'll also link this up with Barwise & Seligman's recent work on 'channels' that partially transmit logics between distributed 'information structures'.
