LOCATION:Room I.401, Diamantslijperij, Nieuwe Acht
 ergracht 170, Amsterdam\n      (Tram 9 from Centra
 l Station, to Plantage Badlaan.).
DESCRIPTION:Abstract.  We study many important pro
 perties of negations using neighborhood semantics,
  including antitony, De Morgan laws, classical dou
 ble negation, constructive double negation and so 
 on. We generalize the correspondence between such 
 properties of negations and the conditions on the 
 frames. Finally we discuss the duality between the
  category of distributive modal algebras with anti
 tone negations and the category of descriptive gen
 erated neighborhood frames.    For more informatio
 n, contact Yde Venema (yde at science.uva.nl)
