The Vasiliev equations generate the unfolded equations for a specific field content, which consists of a one-form ω ω and a zero-form C , both taking values in the higher-spin algebra. Therefore, W A = ( ω ω , C ) and ω ω = ω ω μ μ ( Y | x ) d x μ μ , ω ω ( Y | x ) = ω ω ( − − Y | x ) , C = C ( Y | x ) , C ( Y | x ) = C ( − − Y | x ) . The unfolded equations that describe interactions of higher-spin fields are
