 | | The action of the instanton itself is negative, but the effect of perturbations around the instanton, is to increase the action, that is, to make the action less negative. |
 | | However, a larger instanton, means starting at the north pole, with a lower value of the scalar potential, V. If the form of V is given, this in turn means a shorter period of inflation. |
 | | The a-priori probability from the no boundary proposal wants to make the instantons large, and probabi lity of the formation of galaxies, which requires that both omega, and the amplitude of the fluctuations, not be too small. |
