Note on Using Computers in Math 254 | I tend to use a computer program called PARI-GP to do number theory and elliptic curve calculations. The good news about PARI is that it is free and very fast and powerful at doing number theoretic computations. The bad news is that it's not tremendouly user friendly. You can download PARI by clicking here. Another way to use PARI to do short calculations is to use the SAGE web site. You'll need to create a (free) account. Then you'll be able to type one or more PARI commands and type Shift-Return to perform the computation. Or you can use SAGE itself, which has a large collection of algorithms for working with number fields, local fields, and elliptic curves. |

**Course Goals**:
To learn the fundamentals of the arithmetic of elliptic curves, including
their properties over finite fields, local fields, and algebraic number fields.

**Learning Activities and Time Allocation**:
Learning activities include class attendance, frequent problem sets,
and a take-home final exam. The time to complete these activities are
(1) attending lectures, approximately 3 hours/week; (2) working on the
problem sets and the final exam, approximately 9 hours/week.

**Assessment**:
Course grades will be determined by the quantity and quality of
problem sets submitted (80% of grade) and by their grade on the takehome final exam (20% of grade).

**Expectations of Students**:
It is expected that students will attend all lectures and participate in class discussion
in an appropriate manner.
Assignments are due on the listed dates.
All students are expected to abide by Brown's academic code, which may
found here
