The field of fault-tolerant protocols studies which concurrent tasks are solvable in various computational models where processes may crash. To answer these questions, powerful mathematical tools based on combinatorial topology have been developed since the 1990’s. In this approach, the task that we want to solve, and the protocol that we use to solve it, are both modeled using chromatic simplicial complexes. By definition, a protocol solves a task when there exists a particular simplicial map between those complexes.In this thesis we study these geometric methods from the point of view of semantics. Our first goal is to ground this abstract definition of task solvability on a more concrete one, based on interleavings of execution traces. W...
