I read the book of J B Conway for Complex Analysis. I don't have clear concept about "Branch Point" and "branch cut" of an analytic function. And this topic is not discussed in Conway's book elaborately ...So its too hard to understand it from this book.

So can anyone here please suggest me a good book (or any pdf) from which I can understand this concept. Thank you.

  • $\begingroup$ I have only read Gamelin's Complex Analysis, so that is the only book that I can really recommend. $\endgroup$ – MSobak Aug 24 '18 at 6:44

  • $\begingroup$ If I recall correctly the book "Lectures on Riemann Surfaces" by Otto Forster contains quite a lot about these things. $\endgroup$ – asdq Aug 24 '18 at 8:08

Tristan Needham's award-winning book Visual Complex Analysis explains in detail at an undergraduate level.

You can read Complex Variables and Application by J. W. Brown & R. V. Churchill, in the book the topic is discussed with a few examples though in not much details but a fair amount to get basic ideas.
