AI Thread Summary
The discussion centers around recommendations for rigorous introductions to functional analysis, with a preference for texts similar in rigor to E.D. Bloch's book on real analysis. Several books are highlighted, including Lang's "Real and Functional Analysis," Brezis's "Functional Analysis, Sobolev Spaces and PDE," Lax's "Functional Analysis," Reed and Simon's "Functional Analysis," and Conway's "A Course in Abstract Analysis." The user expresses a particular interest in applications rather than purely theoretical development, indicating that Lax's book may be a suitable choice due to its concise nature and broad coverage of topics.

Is your interest in applications and examples or more towards theoretical development? What would you like to do with it?

More interest in applications actually.., Lax's Book appears to be pretty concise and have a hugh amount of topics, I'm going to try this book.
 

Thread '"WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians'

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...

Thread 'Books with a more theoretical approach to turbulence and DNS'

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...
