This paper is meant for the newbie. it isn't a kingdom­ of-the-art paper for examine employees within the box of regulate concept. Its goal is to introduce the reader to a couple of the issues and ends up in keep an eye on concept, to demonstrate the applying of those re­ sults, and to supply a advisor for his additional interpreting in this topic. i've got attempted to encourage the implications with examples, especial­ ly with one canonical, basic instance defined in §3. Many effects, corresponding to the utmost precept, have lengthy and hard proofs. i've got passed over those proofs. ordinarily i've got integrated in basic terms the proofs that are both (1) no longer too tough or (2) quite enlightening as to the character of the end result. i've got, besides the fact that, often tried to attract the most powerful end from a given evidence. for instance, many present proofs up to the mark idea for compact ambitions and distinctiveness of ideas additionally carry for closed ambitions and non-uniqueness. ultimately, on the finish of every part i've got given references to generalizations and origins of the implications mentioned in that part. I make no declare of completeness within the references, besides the fact that, as i've got frequently been content material purely to refer the reader both to an exposition or to a paper which has an in depth bibliography. IV those 1ecture notes are revisions of notes I used for aseries of 9 1ectures on contro1 concept on the foreign summer time Schoo1 on Mathematica1 platforms and Economics held in Varenna, Ita1y, June 1967.
