Voting, Pizza and Meeting this Wednesday
I hope you all had a wonderful break last week!
Wednesday, December 1, is a BIG day for MGB as there will be an election, pizza, and a meeting.
1. Starting Wednesday morning you will be able to vote for next year's Math Graduate Board officers. Alternatively, you may vote during the general meeting at 4:30 in the Muhly Lounge. The link to the online ballot will be sent Wednesday morning.
2. We will be offering our usual Wednesday noon pizza in the Muhly Lounge. Come grab a sector!
3. We will be having our monthly meeting at 4:30 Wednesday. If you don't like the idea of voting online, you can submit a ballot at the meeting.
We will also be deciding how MGB fundraiser money should be allocated.
Here is a summary of the ballot:
For the offices which will have two winners, candidates are allowed to campaign together, but their names will not be attached in any way on the ballot.

MGB Officer Nominations
The election of new officers is only two weeks away! If you have been nominated for an office, please contact Andrew or Alina to accept/decline the nomination. Office descriptions are available at http://math.uiowa.edu/MathGraduateBoard/index_files/officerinfo.html
GAUSS: The Shadowing Property onn the Unit Interval
Our GAUSS speaker this week is first year math graduate Alex Berrian,
and the title of his talk is "The Shadowing Property on the Unit
Interval." Check the bottom of this e-mail for his abstract. The
main point is this: Alex is going to be talking about analysis
research he did as an undergrad in an REU (Research Experience for
Undergraduates) program, but he would also like to spend some time
talking about REU programs. If you are an undergrad math major then
you should come to GAUSS today to learn about REU programs. We would
like to get you excited about these excellent opportunities to
Experience real mathematics Research. If you are one of the many math
grads who at one point was in an REU or involved in an REU, you are
welcome to come join in the conversation. The final category of
people who should attend are people who like analysis. Snacks will be
provided.

concerning GAUSS feel free to e-mail me or Trent.

Title: The Shadowing Property on the Unit Interval
Date time and location: Tuesday, November 16, 4:30 PM, 118 MLH
Abstract:
Try this with your TI-83 or similar calculator: Punch in .9 and hit
ENTER. Hit the Cosine button, and then hit ENTER. You get cos(.9),
which is about .62. Hit ENTER again, and you get cos(cos(.9)), which
is about .81. Now hit ENTER a whole lot of times. Eventually you'll
get a number close to .74. We call this process an iteration of the
function cos(x). Try doing this again, but start with .1 instead.
Guess what? After a while, you get the same number! Do this with any
number between 0 and 1 and you will arrive at the same result. Cool,
right? But wait - the calculator must truncate its answer each time in
order to do its calculations. How do you know that the calculator's
result for the nth iteration of cos(x) is close to the actual value?
One way of characterizing the accuracy of such an iteration is called
the shadowing property, which cos(x) happens to satisfy on the closed
unit interval [0,1], but which some functions do not. I'll explain
research I did during a summer NSF REU program with two other students
that gives a condition for certain functions to satisfy the shadowing
property on [0,1]. Undergraduates who want to know what REU programs
are like, as well as people who enjoy Analysis like me, are very much
encouraged to attend!

Pizza on Wednesday
Due to the success of last week's pizza fundraiser (we raised
$25!), I will be in the Muhly lounge this Wednesday between noon and
1pm again distributing pizza slices and beverages and collecting your
$2.50 contributions.
MGB has recently made a commitment to raise funds. These monies could
be used for mathematical events organized by us such as SK Day, the
math modelling competition and the AMS Central Section meeting to be
held here in the spring. We hope you will join us this Wednesday for
a slice (or two) !

MGB Meeting this Wednesday
Come to the MGB meeting this Wednesday (November 3, 2010) at 4:30 in the Muhly Lounge to nominate candidates for next year's Math Graduate Board officers. The offices are described at http://math.uiowa.edu/MathGraduateBoard/index_files/officers.html We will also discuss the recent departmental review, a hot chocolate fundraiser in December, math t-shirts, and coffee in MacLean hall.
We hope to see you there!

GAUSS: A Look at the ABC Conjecture via Elliptic Curves
Hi everyone,
The GAUSS speaker today is Gerard Koffi. He's going to be talking
about "A Look at the ABC Conjecture via Elliptic Curves: An Algebraic
Approach." All are welcome to attend, and snacks will be provided.
I'll paste his abstract at the bottom of this message.
If you'd like to keep up to date on what is happening in GAUSS, our
website is http://math.uiowa.edu/~
any questions or comments about GAUSS e-mail either me or Trent, or
talk to us in person, or write one of us a personal letter.
Finally, if you haven't voted already today is the day.

Speaker: Gerard Koffi
Title: A Look at the ABC Conjecture via Elliptic Curves: An Algebraic Approach
When and where: Tuesday, November 2, 2010, 4:30 P.M., 118 MLH
Abstract:
The ABC conjecture is a central open problem in number theory. It was
formulated in 1985 by Joseph Oesterle and David Masser, who worked
separately but eventually proposed equivalent conjectures. Consistent
with many problems in number theory, the ABC conjecture can be stated
in relatively simple, understandable terms. However, there are several
profound implications of the ABC conjecture. Fermat's Last Theorem is
one such implication. We study the connection between elliptic curves
and ABC triples. Two important results are proved. The first gives a
method for finding new ABC triples. The second result states
conditions under which the power of the new ABC triple increases or
decreases. Finally and if time permit, we present two algorithms
stemming from these two results.
