Department of Mathematical Sciences faculty Dr. Emily Barnard and Dr. Karl Liechty have been awarded a grant from the Mathematical Association of America's (MAA) National Research Experience for Undergraduates Program (NREUP) for Summer 2022. Congratulations Dr. Barnard and Dr. Liechty!
The NREUP supports the participation of mathematics undergraduates from historically underrepresented groups, through focused and challenging research experiences, to increase their interest in advanced degrees and careers in mathematics. The 2022 NREUP at DePaul University will provide stipends to four undergraduates as they spend 8 weeks engaging full-time in mathematics research.
The 2022 NREUP at DePaul University will focus on the relatively new field of dynamical algebraic combinatorics. Broadly speaking, problems in dynamical algebraic combinatorics investigate enumerative questions about the orbit of a combinatorially defined map on some algebraic object. We will focus on two key maps on the symmetric group: the pop-stack sorting map and the kappa map. A typical question is: For an invertible map, is the average of "size" of each orbit the same? Our students will build on existing results about the behavior of these maps for the set of all permutations and for permutations which are 312-avoiding to study the maps on other pattern-avoiding permutations. Students will leave with a toolbox for exploring research questions in a variety of interconnected mathematical fields, including dynamical systems, extremal, algebraic and geometric combinatorics, and possibly topology and representation theory.
At the end of the day on June 30, 2021, Professor Ahmed Zayed concluded an incredible 20-year stint as the Chair of the Department of Mathematical Sciences.
Dr. Zayed joined the DePaul faculty in 2001 as the result of a targeted search to hire a new Chair for the Department of Mathematical Sciences. In his term as Chair, Dr. Zayed oversaw many transformations within the department, including the hiring of almost all of the department's current full-time faculty. The Department owes much of its success over the past two decades to Dr. Zayed's steady leadership and administration.
Dr. Zayed will be succeeded as Department Chair by Professor Kyle Petersen.
Effective July 1, 2021, Dr. Yevgenia Kashina has been promoted to the rank of Professor. Congratulations Dr. Kashina!
Dr. Kashina earned her PhD in Mathematics from the University of Southern California in 1999. She then spent one year as a Postdoctoral Research Fellow at the Mathematical Sciences Research Institute (MSRI) in Berkeley, CA, and two years as a Postdoctoral Research and Teaching Associate at Syracuse University, before joining the faculty at DePaul University in 2002. Dr. Kashina's research is in Hopf algebras.
Effective July 2021, Professor Bridget Tenner has been awarded a 3-year $175,000 research grant from the National Science Foundation's Division of Mathematical Sciences to investigate the subject of Higher-Order Pattern Containment. Congratulations Professor Tenner!
From the abstract of Professor Tenner's award:
Permutations are orderings of a set of objects, typically positive integers. They can model aspects of many different problems and scenarios, and they are used throughout mathematics. A permutation pattern is a subset of a permutation that appears in a particular order. For example, it might have an increasing subsequence of some length, or it might avoid having a large number followed by two smaller numbers. The presence or absence of particular patterns can be critical to features of the data that the permutation is modeling, which has led to great interest in the analysis of permutation patterns for the past several decades. The goal of this project is to establish a broader context to the traditional study of permutation patterns. Historically, research in this area has been almost entirely in terms of a binary question: does a permutation contain a given pattern or does the permutation avoid it? Recent evidence has shown that the specific number of times that a pattern appears is of great importance, and consequently a more granular notion of pattern containment should be studied. Specifically, the question should instead be: how many times does the permutation contain the pattern? This project will address that higher-order question in several ways, with implications for combinatorics and its connections to algebra, topology, and computer science.
In August 2021, the Department of Mathematical Sciences will be proud to co-host ARC 2021, the 56th Actuarial Research Conference. This year's meeting will be held virtually online. For more information, visit the conference website go.depaul.edu/arc2021
