Women in Mathematics
Women in Mathematics Seminar
Background:
The mission of the Seminar for Women in Mathematics is to provide a
relaxed, supportive and stress-free environment in which women graduate
students, advanced undergraduate students, postdocs and faculty in the
department can interact. It also provides a place where women may give
talks and discuss mathematics at a level accessible to all graduate
students.
Format:
The speakers for the seminar are female, usually graduate students or
postdocs in the mathematics department. Talks range in length from 30 to
50 minutes, and are at the beginning graduate level. Talks may be on any
mathematical topic, and need not represent original research.

Title: Asymptotic
translation lengths in the complex of curves.
Abstract: In 1981, Harvey
introduced the complex of curves C(S) which captures the combinatorial
structure of a surface S. There is a natural action of the mapping class
group Mod(S) on C(S), hence we can define asymptotic translation lengths
of Mod(S) in C(S) equipped with a metric. We will show that the infinimum
length goes to zero like 1/g^2. This talk will be accessible to a general
audience. (This is joint work with Vaibhav Gadre).

Title: Interaction on
VaR(Value-At-Risk) and CVaR(Conditional-Value-At-Risk) risk measures
Abstract: The
banking industry relies heavily on the VaR to measure risk which
though easy to understand has several shortcomings--it is not
subadditive, not convex in general, difficult to optimize and does
not take into account losses beyond VaR which may be arbitrarily
large. On the other hand, CVaR as a risk measure is preferred in
the academic circles due to its interesting properties of coherence
and the fact that it does take into account losses larger than
VaR. Assuming that a trader thinks in CVaR terms, we study how a
constraint on VaR imposed by the trading firm gets translated to
an interesting and challenging inverse problem and lay down a
framework for solving this inverse problem.

Title: Weak Lefshetz
Property-a computational approach
Abstract: I will begin by
introducing the algebraic counterpart of the famous Lefschetz Property in
differential geometry. Then we shall explore some of the tools that are
available for algebraists to study the Weak Lefschetz property. I will
show how to completely solve the prolem in a particular case. Time
permitting, I will illustrate my talk with computations using computer
algebra software. This talk will be easily accessible to non-specialists.
- October 23: Inmi Kim
Title:Constructions of
Gabor dual window
Abstract:I'll give
you a brief explanation about the Short Time Fourier Transform and
some related theorems. Then we'll see the window conditions for
being dual windows in Gabor system. If we have some restrictions
on our windows, we can get very simplified window condition which
is used for my Gabor dual windows constructions in 1-dimension.
Also, if time is okay, I'll give you further topics such as higher
dimensional constructions and directionally sensitive Gabor
elements.

Fun Activities
- Dessert Night: The Fall 2009 Dessert/Appetizer night will
be held on October 7 at 7:00 p.m.
One of the department's most anticipated ongoing
traditions (and by far the tastiest).
