Math/CS Colloquium Series
Michael Tait, Villanova University
The card game SET, finite geometry, and additive combinatorics
In this talk we will discuss the connection between the card game SET and one of the most famous problems in combinatorics: the cap-set problem.
The cap-set problem and a generalization of it that we will discuss will foray into the worlds of finite geometry and combinatorial number theory. The talk will be accessible to undergraduate students.
This is joint work with Alice Huang and Rob Won.
Dr. Michael Tait is an assistant professor with the Villanova University Department of Mathematics.

Math/CS Colloquium Series
Dr. William Dunham, Emeritus Truman Koehler Professor of Mathematics
How Odd are Odd Perfect Numbers?
Greek mathematicians defined a whole number to be perfect if it is the sum of its proper divisors, where “proper” means the divisor is smaller than the number itself. An example is 6 , because the sum of its proper divisors is 1 + 2 + 3 = 6 . Since classical times, 51 perfect numbers have been found … and every one of them is even.
That raises an obvious question: are there any odd perfect numbers? To date, no one knows the answer. It is one of the true mysteries of mathematics.
In this talk, we trace the history of perfect numbers. This will lead us to an 1888 argument in which J. J. Sylvester proved that, if an odd perfect number does exist, then it must have at least three different prime factors. Although this property is far from self-evident, Sylvester’s elegant proof requires nothing more sophisticated than geometric series.
So, we’ll see a bit of history and a bit of mathematics as we dabble in the challenging realm of number theory.

Rebecca Wright, Director of the Center for Discrete Mathematics and Theoretical Computer Science [DIMACS] - "Privacy In Today's World"
Privacy has become an issue of increasing importance in today’s world of networked computing, mobile devices, the Internet of Things, and large-scale data analysis. This talk describes several privacy
solutions and challenges. Specifically, we demonstrate the use of
differential privacy in the context of human mobility modeling based on fine-grained mobile telephone data. We also discuss “side channels” in Facebook and whether they should be viewed as a privacy problem. Finally, we discuss the potential use of differential privacy in conjunction with secure distributed computation, each of which
provide different kinds of privacy protection.

Armin Mikler, University of North Texas - "RE-PLAN: A Framework for Responding to Biochemical Emergencies"
Emergencies stemming from the release of harmful biochemical substances demand a timely response. Therefore, local governments are required to maintain functional plans for receiving medical countermeasures (MCMs) from the Strategic National Stockpile (SNS) and distributing them within federally-mandated timeframes.
Determining optimal placement of clinics for the distribution of MCMs, requires the integration of geographic, demographic, and transportation data. The design and analysis of these response plans is a complex task. To this end, the RE-PLAN Framework has been developed to facilitate a data-driven response plan design. This talk will provide the highlights of RE-PLAN, a computational framework for placing facilities based on different optimization criteria.
