30 Sep 2008: ii) χ(a) = 0 A sin(ka) = 0 ka = nπ where n = 1, 2,. ... Imposing continuity of χ(x) at x = a gives,. A cos(ka) = D exp(κa) (35).

3 Mar 2020: 1.3 Time-independence. Definition. A spacetime is stationary if it admits a Killing vector field ka whichis everywhere timelike: gabk. ... akb < 0. We can choose coordinates as follows. Pick a hypersurface Σ nowhere tangentto ka and introduce

25 Aug 2021: q. kA(eiqa/2 eiqa/2). Notice that only the combination (r t) appears.

1 May 2020: Ka|p〉 = 0. (7)The n-th order ‘descendents’ of the primary are defined by acting on theprimary with n momentum operators:.
