Abstract:

Let D be a bounded domain with piecewise C(1) boundary in C^n,f∈C(1)(0,q)(D and  f∈C(1) (0,q+1)(D  The anthors establish a new integral formula of Koppelman of (0,q) form with discrete holomorphic kernels on D (-1)qf=Lη D f-(RηD+BD)af+R)ηD+BD)f,where LηDf,RηDf,BDf,RηD-fare some corresponding integral operators.If -f=0, then u=(-1)q(RηD+BD)f is a local differentiabl solution of the equation u=f in D, and u has an inner closed uniform estimate in D, i.e. ‖u‖L∞≤C‖f‖L∞.
