Query: Weak lensing analysis in three dimensions   We present a comprehensive full-sky 3-dimensional analysis of the
weak-lensing fields and their corresponding power spectra. Using the formalism
of spin-weight spherical harmonics and spherical Bessel functions, we relate
the two-point statistics of the harmonic expansion coefficients of the weak
lensing shear and convergence to the power spectrum of the matter density
perturbations, and derive small-angle limits. Such a study is relevant in view
of the next generation of large-scale weak lensing surveys which will provide
distance information about the sources through photometric redshifts. This
opens up the possibility of accurate cosmological parameter estimation via weak
lensing, with an emphasis on the equation of state of dark energy.
