AI Thread Summary
The discussion revolves around the challenges of transitioning from Spivak's Calculus to more advanced texts like Folland's Advanced Calculus and Rudin's Real and Complex Analysis. The participant has achieved an A in their elementary analysis course but acknowledges the generous grading. They find Rudin's text particularly difficult and are seeking recommendations for supplementary materials, specifically asking about Ahlfors' Complex Analysis. Concerns are raised about the jump in difficulty from Spivak to Rudin, with suggestions that Rudin's Principles of Mathematical Analysis may be a more manageable alternative. The participant has learned key analysis concepts such as compactness, Cauchy sequences, and continuity independently, indicating a self-driven approach to their studies. They express a basic understanding of complex analysis but recognize the need for a stronger foundation before tackling Ahlfors, which is noted for its terseness. The overall sentiment highlights the importance of building a solid groundwork in analysis before progressing to more complex texts.

I've just finished an elementary analysis course using Spivak's Calculus. I did get an A in the course but only because the professor was often very generous with the grading. The course I am in currently is using Folland's Advanced Calculus text.

At the same time I have also been studying from Rudin's Real and Complex Analysis which has been moving along really slowly. I find it exceedingly difficult but I still do plan to forge on ahead with it. I asked my professor about another book for more practice and he pointed me to Lar Ahlfors Complex Analysis text. Can anyone comment on Ahlfor's text and compare Rudin and Ahlfors? I am doing this all on my own. I will occasionally ask questions here on physics forums but obviously if the text is too hard it won't help me any as I am already struggling a lot with Rudin.

i haven't used spivak myself, but how much analysis was covered in your course?

for instance, did you learn about compactness, cauchy sequences, completeness, convergence, continuity in metric spaces and normed spaces? it seems to me that going from spivak directly to rudin's Real and Complex Analysis is a pretty big jump. if you aren't able to do the exercises, then maybe you could have a look at rudin's Principles of Mathematical Analysis which may be easier for you to go through since you already have some analysis under your belt.

for ahlfors, have you taken a complex variables class already? ahlfors is also pretty terse so it may be difficult to go through without prior knowledge on the subject.
 
For analysis, I did learn about compactness, cauchy sequences, completeness, convergence, and continuity in metric spaces. The stuff like compactness, completeness, and metric spaces didn't come from Spivak. I learned by basically teaching myself those things. The reason I am attempting to work through big Rudin is because it started as a reading course with the professor. We didn't get very far but I thought I'd continue it anyway. Now that you mention it, I will definitely put down big Rudin and spend a month or so going through baby Rudin first.

As for complex, I only know the most basic things like for example the theorems that have to do with sequences and series in the real plane that can be used in the complex plane. I was also exposed to the proof of the fundamental theorem of algebra and stirling's formula.
 
The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis, etc, it teaches QFT with only a passing acquaintance of ordinary QM you would get at HS. However, I would read Lenny Susskind's book on QM first. Purchased a copy straight away, but it will not arrive until the end of December; however, Scribd has a PDF I am now studying. The first part introduces distribution theory (and other related concepts), which...
I've gone through the Standard turbulence textbooks such as Pope's Turbulent Flows and Wilcox' Turbulent modelling for CFD which mostly Covers RANS and the closure models. I want to jump more into DNS but most of the work i've been able to come across is too "practical" and not much explanation of the theory behind it. I wonder if there is a book that takes a theoretical approach to Turbulence starting from the full Navier Stokes Equations and developing from there, instead of jumping from...
