We compute here the Borel complexity of the relation of isometry between separable Banach spaces, using results of Gao, Kechris [1] and Mayer-Wolf [4]. We show that this relation ...
Recently, a universally composable framework for RFID authentication protocols providing availability, anonymity, and authenticity was proposed. In this paper we extend that frame...
Traditionally, universities focus primarily on instructionist teaching. Such an understanding has been criticized from theoretical and practical points of view. We believe that so...
In a previous paper with M. Dzamonja, class forcings were given which fixed the complexity (a universality covering number) for certain types of structures of size together with ...
