Kinematics of Higher-spin Fields

This dissertation argues a quantum theory for higher-spin fields. Causality is discussed in both classical and quantum senses in a field theory. Renormalizability is also considered. Equations of motion are derived from a generalised concept of linearised Christoffel symbols for these higher-spin fields. It is seen that a minimally-coupled Rarita-Schwinger field violates causality, and that supergravity restores it at a classical level. Then these fields are quantised with generalised polarisation 4-vectors. Feynman rules are constructed in momentum space.
