[...] Is the join calcuclus a monocontextural calculus (as I assume)? How can the join calculus (and distributed processes) be expressed using Gotthard Guenthers polycontextural logic? Is there any research on this topic? As far as I know only polycontextural logic can express parallel, distributed systems (and selfreference) in a complete/total way. So, when join calculus is monocontextural (which it is, if it uses the math we all have learned) it will be a subsystem of what can be expressed with polycontextural logic. It would be fine to have some explanations here, on what the join calculus is capable of. Ciao, Oliver
