## 10/23: Professor Michael Sullivan, “Everything you want to know about option pricing but were afraid to ask”

We will go through the basic mathematics of how to price options. Starting with some simple, but reasonable assumptions we will end

up with a formula that is a simple version of the celebrated Black-Scholes formula (Nobel Prize 1997). This lecture is the essence of Math 441.

## 10/16: Alden Gassert, “Opening Parrondo’s Paradox”

This Wednesday at 5:30 in LGRT 1528 (note the room change), Alden Gassert will present, “Opening Parrondo’s Paradox” (abstract below). As always, we will have free pizza and soda with the talk.

Abstract:

Games of chance are prevalent in our society in both leisure (lottery, casinos) and business (stock market). In most cases these games are heavily biased against the players, yet that does not deter people from playing. Many people make their livelihood creating systems to win despite the odds. In this talk, I introduce a set of biased games and ask the classic gambler’s question: “is there a winning strategy?” You may already be able to guess the answer, but the process we use to answer the question is both unusual and surprising. With this talk, I hope to demonstrate a snippet of why mathematics is such a powerful and wonderful field. The first half of the talk will involve some simple probabilities and will be accessible to (and hopefully enjoyable for) all listeners. In the second half of the talk, I will go deeper into the mathematics involved in our problem to make our results rigorous. Some knowledge of linear algebra will be helpful for this part, but it is not required.

## 10/9: Professor Erin Conlon, “Statistical Methods in Bioinformatics Research”

Please join us for another Math Club talk this Wednesday, 5:30-6:30 in LGRT 1634. This week, Professor Erin Conlon will speak on “Statistical Methods in Bioinformatics Research” (abstract below). This should be a really interesting talk, especially to those of you interested in applied math or statistics.

As always, pizza and soda will be provided. Hope to see you there!

How are genes switched on and off in different activities?

DNA sequence is used to answer this question. This sequence

is represented by 4 letters: A, C, G and T (for adenine, cytosine,

guanine and thymine), and humans have 6 billion of these letters

in each cell. I will present statistical methods for identifying

patterns in sequence that are used as “on-off” switches to activate

and deactivate genes in various environments. The motivation for

this work is to develop treatments for health conditions.

## 10/2: Professor Tom Braden, Graduate School in Mathematics

On Wednesday, October 2, 5:30-6:30 in LGRT 1634, Professor Tom Braden will be hosting a special info session on graduate school in mathematics. Not only is Professor Braden the Graduate Program director here, but he has also served on admissions committees and knows a thing or two about putting together a strong application.

As usual, pizza and soda will be provided. Hope to see you there!

## 9/18: Tobias Wilson, The Intersection of Parallel Lines

On Wednesday, September 18, 5:30-6:30 in LGRT 1528, Tobias Wilson will give the first talk of the semester on “The Intersection of Parallel Lines” (abstract below). As usual, free pizza and soda will be provided.

Hope to see you there!

Abstract:

Two distinct lines in a plane either intersect in exactly one point or

are parallel and never intersect. In this talk, we will reunite those

lonely parallel lines by introducing the notion of projective space.

We will then explore various definitions of projective space and end

by deriving some cool results about curves and tangent lines.
