Shifting and Scaling,the clocks of all processes run at the same rate. The uncertainty in the system arises only from message delays and from differences in the initial values of process variables. Even so, it is possible to derive interesting lower bounds.

Covering Arguments,esulting from applying this primitive does not depend on its current value, then the information stored in the object will be obliterated. In this case, we say that the primitive is . and the process . the object.

Indistinguishability,f a process, including the value of its input variables, is the knowledge the process has about the system. To solve many distributed computing problems, processes need to learn information about the states of other processes. Proofs of unsolvability results show that this knowledge cannot be obtain

Valency Arguments,from some class) lead to the same result. In particular, all final configurations are univalent. Starting from a . configuration, there are two or more different terminating executions (from the class) that each lead to a different result. When there are only two possible results, for example, in bi

Combinatorial Arguments,-free set consensus is unsolvable in an asynchronous shared memory system where processes communicate via registers. Then, in Section 8.2, we prove a lower bound on the number of steps required to perform an Update in a single-writer snapshot object implemented from single-writer registers. In both
