The DBAR problem is the problem of solving the differential equation
for the function , where is assumed to be known and is a complex number in a domain . The operator is called the DBAR operator
The DBAR operator is nothing other than the complex conjugate of the operator
denoting the usual differentiation in the complex -plane.
