The application of the seismic reflection method is often limited in complex terrain areas. The problem is the incorrect correction of time-shifts caused by topography. To apply normal moveout (NMO) correction to reflection data correctly, static corrections are necessary to be applied in advance for the compensation of the time distortions of topography and the time-delays from near-surface we...

Analysis of the first-order corrections to higher-spin equations is extended homotopy operators involving shift parameters with respect spinor $Y$ variables, argument connection $\omega(Y)$ and zero-form $C(Y)$. It shown that a relaxed uniform $(y+p)$-shift by proper form free constitute one-parametric class vertices contains those resulting from conventional (no shift) homotopy. A pure not aff...
