I have not studied complex numbers, but are you saying that the complex logarithm is not a function? I am having trouble understanding what the complex log actually represents or stands for. Is there another way to write the complex log that is more understandable or can you explain it differently? Thank you dear sir.

Every function is mapping or every mapping is function??
