The discussion centers around finding suitable analysis textbooks for an undergraduate student in physics with a limited math background. A recommendation for Serge Lang's "Undergraduate Analysis" is highlighted as a good option, despite the user's initial struggle with Rudin's text. For those with less exposure to formal proofs, advanced calculus texts like Spivak or Fitzpatrick are suggested. Pugh's analysis book is also mentioned for those familiar with formal proofs. Additional resources include a link to free e-books, including one by Ash that offers solutions to problems, which may be beneficial for self-study. The conversation emphasizes the importance of selecting a textbook that aligns with the student's current understanding and needs.
