I bought the fourth edition of Royden Real Analysis, this book is awesome and it's quite different from the third edition, which has less exercises.
I have the solution manual for the third edition. Is there a solution manual for the fourth edition?
I always like doing the exercises by myself, but it is very important for me to be able to verify that they are correctly solved.
This book is such a gem! As a hobby, I've been writing up solutions to the exercises in my free time. You can download them from my website. I've only managed to make it through Chapter 8 though.
I hope you find these useful - my only request is to please let me know if you find any errors :-)
