We show that there is no deterministic local algorithm (constant-time distributed graph
algorithm) that finds a (7-ε)-approximation of a minimum dominating set on planar graphs,
for any positive constant ε. In prior work, the best lower bound on the approximation ratio has
been 5-ε; there is also an upper bound of 52.
