A press company that specializes in applied and scholar mathematics initiated the publication of a series of math problem books for medium through advanced level, with a new different structure.
This editorial project is addressed to undergraduate and graduate students of mathematics institutions, as well as instructors, who can become authors/co-authors of problem books by collecting and editing the problems, according to publishers guidelines.
They also offer benefits and the option for the author to manage his own distribution locally or on the web.
I have registered with them and have chosen the sub-domain Real Analysis Sequences, Series (RAS). I am looking for other two guys to share the authorship of a problem book in this sub-domain, for a quick publication.
