Short cycle connectivity is a generalization of ordinary connectivity—two vertices have to be connected by a sequence of short cycles, in which two consecutive cycles have at le...
We define a class of finite state automata acting on transfinite sequences, and use these automata to prove that no singular cardinal can be defined by a monadic second order formu...
We discuss the tensions between intensionality and extensionality of spatial observations in distributed systems, showing that there are natural models where extensional observati...
