MASSLESS FIELDS IN PLANE-WAVE GEOMETRY

Conformal isometry algebras of plane wave geometry are studied. Then, based on the requirement of conformal invariance, a definition of mass lessness is introduced and gauge invariant equations of motion, subsid iary conditions, and corresponding gauge transformations for all plane wave geometry massless spin fields are constructed. Light cone repres entation for elements of conformal algebra acting as differential oper ators on wavefunctions of massless higher spin fields is also evaluate d. Interrelation of plane wave geometry massless higher spin fields wi th ladder representation of u(2,2) algebra is investigated. (C) 1997 A merican Institute of Physics.
