The unfriendly partition conjecture is an unsolved problem asking whether every countable graph has an unfriendly partition into two subsets. [ 1 ] Robert H. Cowan and William R. Emerson, in unpublished work, conjectured that every infinite graph has an unfriendly partition into two subsets.

His proof of Freiheitssatz and of the solution of the word problem for one-relator groups was based on this approach. Later Moldavansky simplified the framework and noted that in this case G itself is an HNN-extension of L with associated subgroups being Magnus free subgroups of L.
For a given problem, average-case hardness implies worst-case hardness, so an average-case hardness assumption is stronger than a worst-case hardness assumption for the same problem. Furthermore, even for incomparable problems, an assumption like the exponential time hypothesis is often considered preferable to an average-case assumption like ...
Bayesian persuasion is a special case of a principal–agent problem: the principal is the sender and the agent is the receiver. It can also be seen as a communication protocol , comparable to signaling games ; [ 2 ] the sender must decide what signal to reveal to the receiver to maximize their expected utility .

The isomorphism problem was formulated by Max Dehn, [1] and together with the word problem and conjugacy problem, is one of three fundamental decision problems in group theory he identified in 1911. [2] All three problems, formulated as ranging over all finitely presented groups, are undecidable. In the case of the isomorphism problem, this ...
