The Math Department welcomes our new PostDocs in Fall 2024:

Charlotte Aten received her PhD from the University of Rochester in 2022 under the direction of Jonathan Pakianathan. Her research interests lie at the intersection of universal algebra, combinatorics, and category theory. She enjoys exploring connections with algebraic topology, computer science, and logic.

Spencer Daugherty completed their PhD at North Carolina State University in 2024, advised by Laura Colmenarejo (NCSU) and Sarah Mason (WFU). Their research interests are enumerative and algebraic combinatorics, in particular, combinatorial Hopf algebras, quasisymmetric and noncommutative symmetric functions, the Tamari lattice, parking functions, and chromatic symmetric functions.

Juan Villarreal received his PhD in 2018 at the Instituto de Matemática Pura e Aplicada in Rio de Janeiro, Brazil, under the direction of Reimundo Heluani.

Math For All in Boulder DEI Impact grant renewed for the 2024-2025 academic year. Anonymous (not verified) Tue, 08/13/2024 - 02:00

The Diversity, Equity and Inclusion (DEI) Impact grant from the office of the Vice Chancellor for DEI at CU Boulder together with funds from the National Science Foundation and the Mathematics department will support the programming of Math For All in Boulder for the 2024/2025 academic year.

The organizing team consisting of Dr. Fuster Aguilera, Assistant Professor Orosz Hunziker and Associate Professor Czubak first obtained the DEI Impact grant in 2023.

Past Math For All in Boulder activities included Mates para Todes, several poster workshops for undergraduates in the Front Range Area and the Math For All in Boulder conference which took place in April 2024 with 68 participants in the CU Boulder campus. The 2024 edition of the Math For All in Boulder conference, an event designed to “provide a friendly and open environment to learn and discuss mathematics”, consisted of 14 undergraduate poster presentations, 6 graduate student research talks and two plenary talks together with networking and community building activities.

For the coming year, the Math For All programming will include a second edition of Mates para Todes on Oct 25 2024, a colloquium talk in the Math Department with Professor Pamela Harris on September 12 2024 and the 2025 edition of Math For All in Boulder conference in the Spring 2025.

Congratulations to Dr. Fuster Aguilera, Dr. Orosz Hunziker and Dr. Czubak for the DEI Impact grant renewal!

The summer school on C*-Algebraic Quantum Mechanics and Topological Phases of Matter (CU Boulder, July 29 - August 2, 2024) will explore new developments at the intersection of condensed matter physics, C*-algebraic quantum mechanics and algebraic topology. It is organized by Agnès Beaudry (CU Mathematics), Mike Hermele (CU Physics), Markus J. Pflaum (CU Mathematics), and Daniel D. Spiegel (UC Davis).

Robin Deeley promoted to Associate Professor and awarded NSF-grant

Robin Deeley promoted to Associate Professor and awarded NSF-grant Anonymous (not verified) Fri, 11/03/2023 - 12:15

Robin Deeley was promoted to the rank of Associate Professor and was granted tenure. Deeley specializes in index theory and dynamical systems, and came to our department in 2017 as an assistant professor.

He also won a three-year National Foundation Science Fellowship entitled: “C*-algebras associated to minimal and hyperbolic dynamical systems" starting August 2023. This supports Dr. Deeley's research on invariants used to study and classify highly abstract objects. The key properties of a useful invariant are that it is computable and distinguishes many different objects. For dynamical systems, an important class of mathematical objects, the construction of invariants can be very involved. Dr. Deeley will use this NSF funding to study invariants of dynamical systems defined via abstract operator algebras and K-theory. The project will also involve significant contributions from early-career researchers, graduate students, and undergraduate students, who will benefit from training through research involvement.

Meet a Mathematician (MEET)

Meet a Mathematician (MEET) Anonymous (not verified) Tue, 09/05/2023 - 17:09

Meet a Mathematician (MEET) is a collection of video interviews with mathematicians from various career stages and diverse backgrounds. MEET goal is to create a consistent collection of video profiles of mathematicians from underrepresented groups and for students to access stories of modern day mathematicians from underrepresented groups.

These interviews highlight the accomplishments and struggles of mathematicians as well as their field of work and their story of becoming a mathematician. In the interviews, each mathematician provides a brief description of their work in an accessible way and more than 30 fields of mathematics (from number theory to machine learning) are highlighted in the MEET collection. This project was created in 2020 by Drs. Padi Fuster Aguilera and Selvi Kara.

Padi Fuster Aguilera awarded an NSF MPS-Ascend Fellowship Anonymous (not verified) Tue, 09/05/2023 - 17:06

Dr. Padi Fuster Aguilera has been awarded a National Science Foundation Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (NSF MPS-Ascend) to conduct a program of research, education, and activities related to broadening participation by groups underrepresented in STEM. This fellowship supports the research project entitled "Fluid Equations and Chemotaxis on Manifolds". The project activities will be conducted at the University of babyֱ��app Boulder under the mentorship of Dr. Magdalena Czubak.

This project includes research on two related topics in partial differential equations (PDE) and differential geometry. The first one is the search for an intrinsic viscosity operator on a general Riemannian manifold which is of great importance for understanding the appropriate formulation of the Navier-Stokes equations on curved manifolds. The second one is the study of the qualitative behavior of solutions for a PDE model for chemotaxis in curved manifolds with an application to tumor growth in organs. The broadening participation activities for this project include Meet a Mathematician and the Math For All conference. Meet a Mathematician is a collection of video interviews of mathematicians from diverse backgrounds where their personal stories as well as the math research that they do is highlighted with the aim of providing role models for students. Math For All is a nationwide mathematical conference featuring speakers from diverse backgrounds with the main goal of creating a friendly and welcoming environment to discuss mathematics.

We’re delighted to welcome Flor Orosz Hunziker as our newest tenure track hire in the mathematics department. Her work on vertex operator algebras has wide-spread connections and will not only bridge numerous existing groups within the department (algebra, representation theory, combinatorics, algebraic geometry, and topology), but also strengthen some of our ties to other departments such as physics.

Local-Global Conjecture disproved in summer project

Local-Global Conjecture disproved in summer project Anonymous (not verified) Mon, 08/21/2023 - 08:59

This summer, as part of the Department's Summer Research Experience for Undegraduates and First-Year Graduate Students, graduate student Summer Haag, undergraduate Clyde Kertzer, postdoc James Rickards and professor Katherine E. Stange had a surprise discovery; the twenty-year old Local-Global Conjecture for Apollonian circle packings is false! Integer Apollonian circle packings, like the one shown at right, have circles whose curvatures are integers. The image at right colours the circles according to the curvature modulo 3, showing that only integers congruent to 0 or 2 modulo 3 can appear. The conjecture held that, aside from finitely many exceptions and some congruence conditions like the mod 3 restriction in the picture, every sufficiently large integer should appear as a curvature in a primitive integral Apollonian circle packing. The team proved the existence of some new obstructions: for example, some packings cannot admit square curvatures. The proof depends on quadratic and quartic reciprocity.

The result was covered in Quanta Magazine.

Summer Haag, Clyde Kertzer, James Rickards and Katherine E. Stange disprove the Local-Global Conjecture for Apollonian circle packings in a summer research project.
