# Theory of Cosmic Microwave Background Polarization

@article{Cabella2004TheoryOC, title={Theory of Cosmic Microwave Background Polarization}, author={Paolo Cabella and Marc Kamionkowski}, journal={arXiv: Astrophysics}, year={2004} }

These lectures introduce some of the basic theory of cosmic microwave background (CMB) polarization with the primary aim of developing the theory of CMB polarization from inflationary gravitational waves, as well as some of the related theory of weak gravitational lensing (cosmic shear) of CMB polarization. We begin with production of polarization by Thomson scattering. We then discuss tensor-harmonic analysis (the ``grad-curl'' or ``E-B'' decomposition) on a flat and full sky in some detail…
