These will eventually contain the separate Problems set assignments for Fall 2018 Quarter:

4. *1st Problem Set: 2 lines in ***R**^{3} *and finding particular continued fraction:* We expand last Friday's lecture on lines in **R**^{2} to consider lines and planes in **R**^{3}. This plays into discussing how perspective and projectivity geometry works. Then, we solve the problem in the text of finding the continued fraction expansion of the squareroot of 3, by first finding the quadratic irrationality with continued fraction expansion [*t*_{1},*t*_{2},*t*_{1},*t*_{2},…].

5. *2nd Problem Set:*

- Motivation for the
**F**(undamental) ** T**(heorem) of ** A**(lgebra), which reminds of topics in class.
- Problem 1: Cotes' formula: I outline doing a problem that is in the text that appeared in integrating the function 1/(1-
*x*^{n}).
- Problem 2: Fractional power series for
*P(y) - x=0*, with *P* a monic polynomial. This started with Newton, but became a serious tool in many studies of curves in the projective plane, especially for Riemann.

6. *Final Exam:* (with answers) for History of Math 4820.

These will eventually contain the procedures and assignments for class projects:

7. *1st Potential Project: relate Euclidean Algorithm and Pell's Equation:* The Euclidean algorithm applied to (*r*_{0},*r*_{1}) is equivalent to looking at the continued fraction expansion of *r*_{0}/*r*_{1}. Between *Baskara* and *Lagrange*, that leads to always being able to solve *x*^{2}-*Ny*^{2}=1. A project would consider what this is a special case of, and why it was important.

8. *2nd Potential Project: Projective Geometry*: This project will use problems from the book to enhance the following topics.

- The road to Projective Geometry: An expanded review of relating Euclidean to Projective geometry.
- A reason for Projective Geometry: How adding points at ∞ and introducing homogenous coordinates can make seemingly different figures in the plane very much alike.

9. *3rd Potential Project: Polynomial version of Euclid's algorithm, and how it relates to Bezout's Thm.*: This project will use problems from the book to enhance the following topics.

- Simplying the Euclidean Algorithm for polynomials.
- How much we can learn from the case
*P* is a quadric polynomial.
- Reminders on linear algebra and Cramer's Rule.
- Using the quadric case to do the analog of the general resultant.

10. *4th Potential Project: Galois's Group attached to an irreducible polynomial P(y) over ***Q**

- The smallest field containing all the roots of
*P(y)*.
- The definition of Field automorphisms and
*G*_{P}.
- When
*G*_{P} is abelian.
- The primitive element theorem.

4thProj-SymmGalGp.pdf
11. *5th Potential Project: The genus of a curve, a relation between Theorems of Abel, Galois and Riemann.*:
This project uses Puiseux expansions, that they give a field similar to the complex numbers, and that from them we produce permutations of the roots of *P(x,y)* with *y* given as functions of *x*.

- A homogeneous
*p(x,y,z)* defines a map *C*_{p}→ CP^{1}.
- The Puiseux series on
*C*_{p} for *x'*
- Between Galois and Riemann
- Definition of the genus of
*p*

12. *6th Potential Project:* There are diophantine equations over **Z** for which having a **Z** solution is undecidable.

- Consider Galois's Problem.
- The notion of a diophantine set.
- The role of Pell's equation.

Project Summary Notes:
We have six projects, and for each, while listening to them, I will be adding comments that should make an appearance in the appropriate report of your team. Some of the comments consists of observations that should help you understand the point of the project. Some of those comments could be questions on the final.

13. *ProjectSummaryTopics*: There are six projects. These extra comments are foremost meant for the team presenting the topic. As teams finish I will add to the pdf file, until all projects are, by the end of the semester, represented.

The point of my doing this is to show that there are connections between all of the topics. It is those connections that help make the material more memorable than they would otherwise have been. Some of the quick questions could well appear on the final. Of course, you can ask me about such questions in class.
