Integration in respect to a complex measure One can define the integral of a complex-valued measurable function with respect to a complex measure in the same way as the Lebesgue integral of a real-valued measurable function with respect to a non-negative measure , by approximating a measurable function with simple function s. Just as in the case of ordinary integration , this more general integral might fail to exist , or its value might be infinite ( the complex infinity ) .
