Conway Functional Analysis Homework Solutions
Melvin Amey
I am a Ph.D. student in economics and I plan to study functional analysis by myself either this winter or the next summer. I am currently looking for a textbook, and since I am studying it by myself, I would like the textbook to have complete solutions to all or at least many (say, all odd numbered) problems. I have taken a graduate real variables sequence, but have never studied functional analysis before. So preferably, this doesn't have to be a very advanced text.
Try Functional analysis, sobolev spaces and PDE's by H. Brezis. It's got a rather large collection of problems, with solutions. P.R. Halmos' "A Hilbert space problem book" is another very nice reference.
I am first year graduate student and I have taken Functional Analysis course this semester. The main book of teaching is Conway's book "A Course in Functional Analysis" but the lecturer is notorious for giving exams from questions that are not exercises of the book he's teaching. So I need an accompanying book for functional analysis with lots of cool problems that covers same materials of Conway's book and is on graduate level. Any suggestions would be much appreciated.
As people have recommended in the comments, Rudin is a good book for exercises and as a complementary book, but I would not recommend studying from it. Also, Kreyszig's book is a standard functional analysis textbook: don't underestimate it just because it is considered undergraduate. Graduate students can learn much from this book too.
Keep in mind that they are aimed at undergraduate students, so they might not be really close to what you are looking for. But, for example, the standard topics of "The big three theorems" or the Hahn-Banach theorem are nicely addressed. Moreover, there are many important exercises included that someone might have missed in their first functional analysis course.
I'm a student (I've been studying mathematics 4 years at the university) and I like functional analysis and topology, but I only studied 6 credits of functional analysis and 7 in topology (the basics). What I am looking for is good books that I could understand to go deeper in this areas, what do you recommend? (I can read in Spanish, English, French and German)
I'd recommend the Dunford and Schwartz. It's a classic. It's huge -- three volumes. But you don't have to read the whole series cover-to-cover. If you read half of the first volume, you'll learn about as much as reading many other books on functional analysis. Volume 1 alone is big, but it's easy to read for a book on its subject.
Apart from the classics already mentioned (Yosida, Brezis, Rudin), a good book of functional analysis that I think is suitable not only as a reference but also for self-study, is Fabian, Habala et al. Functional Analysis and Infinite-Dimensional Geometry. It has a lot of nice exercises, it's less abstract than the usual book and provides a lot of "concrete" theorems.
I personally like a recent book of Helemskii Lectures and Exercises on Functional Analysis. One of the differences with other books on the subject is that it uses the categoricalpoint of view. The author starts with a very brief introduction to the category theory and uses this language throughout the book. It's a sort of modern core of FA book, with a sidelines to some physics applications and of historic nature, a terse advertisement of the quantum functional analysis and so on (but there is no measure theory, Radon Nikodym theorem etc. which are elaborated in many excellent old textbooks.) Also it gives somewhat broader picture of FA sketching some directions and stating from time to time theorems without proofs 'that every student should know'.
is quite comphrensive and contains beside standard functional analysis more advanced sections on the theory of locally convex spaces. There is also a German version if you want to improve your German by reading both together.
I second Reed and Simon's methods of mathematical physics. However, if you are interested primarily in the applications of functional analysis to PDE, for the most part a couple of appendices of Evans' book suffice in my opinion.
Both Rudin Functional and Conway Functional are mathematical concepts used to describe certain properties of functions. The main difference between them is that Rudin Functional is used in complex analysis, while Conway Functional is used in functional analysis.
Rudin Functional and Conway Functional are used in various areas of mathematics, such as complex analysis, functional analysis, and harmonic analysis. They are also used in physics and engineering to study the behavior of systems described by analytic functions.

Prerequisites: Math 220A. However, this is a graduate level course, so at times, we may use notions from related fields, including topology and real analysis. I am happy to discuss prerequisites on an individual basis. If you are unsure, please don't hesitate to contact me. Grading: There will be a take home Midterm on Friday, February 12, as well as a Final Exam on Wednesday, March 17, 3-6PM. The final grade is based on homework (30%), midterm (30%)and final exam (40%). The problem sets are mandatory and are a very important part of the course. The problem sets are due on Fridays on Gradescope. In order not to interfere with lecture time, there will be a grace period on gradescope.
Clever tech we shouldn't need: Many in the software world prize clever solutions to complex problems, yet often those clever solutions result from self-inflicted accidental complexity. Rather than jump to more technology to solve a problem, teams should do root cause analysis, address the underlying essential complexity and course correct.
