"Upper and Lower Bounds for Stochastic Processes" is the topic to which I devoted a large part of my life. If you are interested in it, my advice is that you should go directely to my 2021 book with this title and IGNORE all the previous books, into which I put far less pedagological efforts. This book is a MAJOR remodeling of the 2014 edition, and furthermore presents the solutions of many 30+ years problems. These solutions have not been published elsewhere. You may find a useful part of the book here. And here are some thoughts related to one of my long-standing matching problems which occurred to me too late to be included in the book. There will be no further editions of this book, but if you have some comments that could help others please share them with me and I will try to make them available.
Here you can find some endorsements for my book "What is a quantum Field theory?" (No, this is not an unbiased sample of opinions. Yes, all these people are my buddies.) Please DO NOT BE SHY to contact me to help you read this book. This will be a considerable help to write the Erratum.
Since the solutions of the exercises are not so easy to find on the publisher's site, I provide here a version where some of the mistakes pointed out in the erratum have been corrected: solutions to selected exercises .
In my youth I have published some papers in the Bulletin des Sciences Mathematiques, of which there does not exist an electronic version. You may find several of them here: Papers in Bull. Sci. Math.
It was a long way to get there.
