Reading this article I became curious to learn more of (- study more thoroughly and *seriously*$^{\star}$-) the topic.
Is / are there some good references - either papers, books and/or other information content / sources - to provide a good (and, if possible, thorough) first introduction?
Would be greatly helpful; and greatly appreciated.
