Let Lm,E be the mth order invariant Cauchy-Riemann operators on Hermitian bun-dles E over Kahler manifold M, given some conditions, Lm,E will be the polynomials of L1,E.In the paper, formula (16) is obtained when Riemannian surfaces are considered; and sup-pose E is the canonical bundle over Bn, then the following formula holds: Lm,E=(?)(L1,E+(j-1)(j-2)) |
