and the alternative expression of u over z > 0 in terms of the boundary values of (du/dz) given by: 1 f Tdu \ dx' dy' ,, " —2^ 7 L^iJ ~k— <13) Here the integration is carried out over the plane z — 0, denoting the element of solid angle subtended at P by the plane element dx'dy' at P', while [m], [du/dt], [du/dz] (1.4) denote the retarded values of these functions at P', that is their values at P' not at the time t, but at the time t' = t — R/c, where R is the distance PP'. The "retarded time" (1.5)
