The Topological Structure of Asynchronous Computability

Herlihy and Shavit identified necessary and sufficient conditions which must be satisfied for a class of distributed computing problems to be solvable. Specifically, they consider asynchronous systems with shared memory in which processes may fail. The characterization is based on notions from topology. Inputs and outputs are modelled as topological structures. The problems considered have a solution if and only if these structures satisfy some topological properties. In this talk, their modelling framework is reviewed and its use to prove properties about certain distributed computing problems is presented.
