9. E is the direction of the electric field. If we add all the contributions of the director around the disclination, the dielectric response becomes independent on the direction of the disclination.
10. 3, 0, 0). Here a is a parameter which indicates the effective range of the disclination. The polarization is practically perpendicular to the disclination.
