However, this only defines the partial equilibrium. To complete the equilibrium we need to use the symmetry (which is also why the subscripts are dropped above):
:<math>a = \sum_{j \ne i} h(x_j) = (n-1)h(x^*)\;</math>
This equilibrium exists providing R&D is profitable absent rivalry (otherwise their may be a corner, not an internal solution).
