(As of 10Jan2006) Welcome to Elem. Number Theory S2006: MAS4203 3173 INTRO.NUMBER.THEORY MWF5 LIT223 Prof. Jonathan King squash@math.ufl.edu Dept. of Mathematics http://www.math.ufl.edu/~squash/ 402 Little Hall (Top floor, NE corner) 392-0281 x270 ================================================================ What primes are SOTS (the Sum of Two Squares)? Is there a finite number of squares that represent ALL positive integers? How does public-key cryptography use NT, and what does the "Euler Phi Function" have to do with it? :::::::::::::::: Our textbook is Fundamentals of Number Theory by William J LeVeque. It is published by Dover Publications. ISBN: 0-486-68906-9 which is in the UF bookstore, and other local bookstores. As the semester progresses, you will also need to print-out a few pages of handouts that I have prepared for you, We will cover some material that is not in our text; in particular, some primality-testing algorithms. SYLLABUS: Chapters 1-8 (Legendre's Thm, Pell's Equation) as well as the cryptography material. REQUIREMENT: You will need to be able to print out POSTSCRIPT (.ps) files, and PDF files. Please install (free) postscript-printing software ASAP. Teaching Page: http://www.math.ufl.edu/~squash/teaching.html Course Page: http://www.math.ufl.edu/~squash/course.numt1.2006g.html Archive: http://www.math.ufl.edu/~squash/NTArc/maillist.html Please keep our archive private to our class. There will be four or three exams, A,B,C, (D). Exam A will have a take-home part (A-home) and an in-class part (A-class). For the take-home you will work in TEAMS of (usually) 3 students. The take-home must be carefully typed and proofread. You will have about 1 week for the take-home part. Each student needs to be in Gainesville during all the week of the exam, as you are responsible to your teammates. Take-home exams are open notes/library and you may use calculators and computers. Each student takes the in-class part individually; his score on A is that of A-home plus A-class. Exams B,C,(D) run similarly, but the last exam will have no in-class component. The last take-home will be due around the last week of class, probably on Thursday 27April, or on Friday morning 28April. There will be NO final exam. The in-class exams are open-brain, closed book/notes/calculators. Dates of exams are to be determined. There will also be a small number of "miniscores"; quizzes, graded-hw, in-class presentations... ADDITION: On Friday, 10March2006, class is canceled. (It is the class-day before Spring Break.) Also the inclass components of the exams will be given in evenings, so that you can have a full 90minutes to work on them. ================================================================
