Abstract
We consider the existence problem for ‘Steiner networks’ trivalent graphs with 2π/3 angles at each junction in strictly convex domains with ‘Neumann’ boundary conditions For each of the three possible combinatorial possibilities sufficient conditions on the domain are derived for existence In addition in each case explicit examples of nonexistence are given
