Abstract: In this paper,we discussed the local integral solution operators of imhomogeneous Cauchy Riemann equations on an open set with piecewise C^k boundary in Cⁿ,as a generalization of the solution opertators for Leray map S(z,ζ) which do not depends holomorphic on z∈D in Koppelman formula is obtained and the L^s norm estimates for the solution operators are the same as that [10] in forms.
