Spinor fields at spacelike infinity
The paper investigates the equation: what form does the boundary value of an arbitrary spinor field take at spacelike infinity, given that the field satisfies a specified differential equation? The spinorial description of angular momentum is discussed and some ideas are given to understand the form of the limits of twistor fields at spacelike infinity. Results are generalized on the leading order behavior of fields of spin 0, 1 and 2, with specified regularity of spacelike infinity to massless fields of arbitrary half-integer helicity and arbitrary regularity.
