Summer
Research Program 2024
Organizers: Alex Iosevich and Azita Mayeli
Dates: July 29 - August 9, 2024
Structure of the program: The program is going to
consist of supervised research projects and series of lectures
designed to help gain the necessary background as you are working on
your projects. The exact topics of the lecture series will be
determined in the coming weeks. The exact topics for the research
projects will be selected based on your interests and preferences.
This program is partly a culmination of undergraduate research
activities that have transpired during the academic year. Once the
program is over, the research projects are likely to continue into
the Fall 2024 semester and beyond.
Application process: Please fill out an on-line
application form at the following
link. The students at all the Rochester area colleges
and universities are welcome to apply.
Projects:
Exact signal recovery
Project supervisors: Alex Iosevich and Azita Mayeli
1) Project description: Suppose that a signal of length N is
transmitted via its discrete Fourier transform and some of the
signal is lost in the transmission due to noise or interference.
Under what conditions is it possible to recover the original signal
exactly? This innocent looking question quickly leads to some
interesting techniques and ideas from analysis, combinatorics and
other areas of mathematics. We are going to investigate these types
of questions from both the theoretical and computational points of
view.
Project participants: Karam Aldahleh
(kaldahle@u.rochester.edu), Gabe Hart (ghart3@u.rochester.edu),
Alhussein Khalil (akhalil3@u.rochester.edu), Aiden Rohrbach
(arohrbac@u.rochester.edu), Terrence Wong
(twong15@u.rochester.edu),
2) Buffon Needle Problem
Project supervisors: Alex Iosevich and Matthew Dannenberg
Project description: This project is continuing from last
summer. The question is, which convex domain K in d-dimensional
Euclidean space with a boundary with a fixed (d-1)-dimensional
Hausorff content maximizes the Buffon probability? Here the Buffon
probability p(K,r) is the probability that if one end of a needle of
length r lands in K with uniform probability, then the other end
also lands in K. Last summer, William Hagerstrom, Gabriel Hart, Tran
Duy Anh Le, Isaac Li, and Nathan Skerett essentially resolved this
question in two dimensions. They proved that given any convex set K
in the plane where the length of the boundary is equal to 2 pi,
there exists a threshold r_0 such that if r<r_0 and K is not the
unit disk D, then p(K,r)<p(D,r). The purpose of this year's
project is to extend this result to higher dimensions.
Project participants:
3) Automated theorem proving
Project supervisors: Alex Iosevich, Azita Mayeli and
Stephanie Wang
Project description: The purpose of this project is to
independently develop some automated proof methods. After an
introduction to the subject matter based on materials provided by
Professor Yifan Zou, we are going to write design and write some
automated theorem proving code. More details will be added in the
coming weeks.
Project participants:
4) Kolmogorov complexity and Hausdorff
dimension
Project supervisors: Alex Iosevich, Azita Mayeli and Svetlana
Pack
Project description: The purpose of this project is to
understand the emerging connections between Kolomogorov complexity
and Hausdorff dimension, with applications to configuration
problems, complexity of graphs and machine learning.
Project participants:
5) Numerical solutions for partial
differential equations
Project supervisors: Alex Iosevich
Project description: The group will use deep learning
methods to investigate solutions of various partial differential
equations. In particular, they will investigate how to solve the
high latitude heat equation using a neural additive model. The group
will also work on other SPDE related problems if time permits.
Project participants: Yuning Ren
(yren29@u.rochester.edu), Kunxu Song (ksong12@u.rochester.edu),
Xiaoya Tan (xtan14@u.rochester.edu), Jingwen Xu
(jxu85@u.rochester.edu)
6) Graph theory and cycle double-covers
Project supervisors: Gabe Hart and Alex Iosevich
Project description: A cycle double-cover of a graph G is a
set of cycles in G such that every edge of G is included in exactly
2 of the cycles. The cycle double-cover conjecture states that every
bridgeless graph has a cycle double-cover. We will investigate this
conjecture and related problems using both theoretical and
computational methods.
Project participants:
7) Math education modeling methods
Project supervisors: Anuurag Kumar and Stephanie Wang
Project description: At present, the United States severely
underperforms in mathematics relative to its global standing,
leading to countless attempts to aid STEM students. Lesser studied,
however, is pedagogy at the undergraduate level, and the factors
that go into attracting and retaining math major students. In this
group, we will explore the variety of factors that contribute to the
undergraduate mathematics experience through a first-generation
lens, including, but not limited to: allocation of university
resources, available mathematical support, community openness,
perceived mathematical stigma and career trajectory, etc. Students
in this group can expect to do mathematical modeling of demographics
and statistical analysis, as well as learn how to apply quantitative
measurements to subject data (interviews, surveys, etc.). Coding
will be done in Python and/or R, and use of ChatGPT is welcome and
even encouraged so far as the programmer understands the code
produced.
Project participants:
8) Random walks and finite graphs
Project supervisors: Alex Iosevich and Anuraag Kumar
Project description: We are going to study random walks on
graphs using Markov chain methods. The goal is to determine accurate
distributions of hitting times.
Project participants:
9) Erdos distance problem on manifolds
Project supervisors: Alex Iosevich and Nathan Skerrett
Project description: The classical Erdos distance problem
asks for the smallest possible number of distances determined by n
points in Euclidean space in dimensions two and higher. In this
project we are going to investigate this problem on Riemannian
manifolds.
Project participants:
10) Physics project
Project supervisors: TBA
Project description: TBA
Project participants:
11) Sales modeling with economic indicators
Project supervisors: Alex Iosevich and Azita Mayeli
Project description: We are going to build and test neural
network models with economic indicator regressors to effectively
predict future sales in retail. A variety of neural network models
will be built using tensorflow, keras, facebook prophet and others.
Theoretical aspects of this problem will be considered as well.
Project participants:
12) Forecasting medical data using neural networks
Project supervisors: Alex Iosevich, Azita Mayeli and Svetlana
Pack
Project description: We are going to work with large swaths
of medical data, including EEG, seizures and others, and look for
identifiable patterns using neural network analysis and more
elementary statistical techniques.
