comment A question from Otto Forster’s book on Riemann surfaces
Thanks a lot! I think the two books you provided seem to be much more readable for me.

comment A question from Otto Forster’s book on Riemann surfaces
Actually I asked the very same question again, and corrected the terrible math writing by simply adding "`" in front of every dollar sign just as suggested. I don't know why, and it seems to happen when you type subscripts。

comment A question from Otto Forster’s book on Riemann surfaces
Thank you so much, Professor Ben Mckay. I will check this out. Actually, I am taking part in a reading course where Forster's book is assigned as the textbook. It's a wonderful book, despite those two problems I have asked, and maybe more. Since you are both familiar with Forster's book and with Riemann surfaces, is there any other nice books you can recommend me to take as a reference? I really appreciate your help and hope to hear from you!

comment Is there an analog of determinant for linear operators in infinite dimensions as that of finite dimensions?
Thank you Professor Israel. Now everything is perfectly understandable!

Thank you so much Qiaochu. It just occurred to me that I've run into the stuff of viewing determinant as actions on top exterior forms when studying smooth manifolds, but your comments for infinite case is really inspiring and I really appreciate your help!
