Shifted homotopy analysis of the linearized higher-spin equations in arbitrary higher-spin background
Shifted homotopy analysis of the linearized higher-spin equations in arbitrary higher-spin background
Analysis of the first-order corrections to higher-spin equations is extended to homotopy operators involving shift parameters with respect to the spinor $Y$ variables, the argument of the higher-spin connection $\omega(Y)$ and the argument of the higher-spin zero-form $C(Y)$. It is shown that a relaxed uniform $(y+p)$-shift and a shift by …
