I love your book xxx xxx xxx (a mathematical book).

Recently I find some minor errors in it (maybe I am wrong), which I would like to discuss with you below.

Page 18, Exercise 1.3.5(c): I guess sup(cA) should be inf(cA) since A is only bounded above and c<0.

This might impare the rigorous flavour of this book.

OseeAs titled, could you please modify it as possible as you can,I think you should add in at the beginning that you have used the book and found it good and helpful.

I would be very interested in your comments on these, and shall look forward to hearing from you.
