Geometry and Topology Seminar: Igor Zelenko, Texas A&M University, Gromov’s h-principle for corank two distribution of odd rank with maximal first Kronecker index
SAS 3282The natural question is: do structures satisfying given open relations (called the genuine solutions of the differential relation) exist on a given manifold? Replacing all derivatives appearing in a differential relation by the additional independent variables one obtains an open subset of the corresponding jet bundle. A formal solution of the differential relation is a…

Doctoral Exam: Evan Curcio, NC State, Mathematical Modeling of Stomach Morphogenesis and the Biomechanics of Pattern in Notochords
SAS 3282This dissertation presents three treatments of mathematical modeling to two relevant areas of biological application.We apply foam physics to the morphometry of cell packings of notochords, elastic membrane physics to notochord biomechanics, and the theory of morphoelasticity to morphogenesis in the developing stomach. The notochord is the defining feature of chordates, and during development it lengthens the embryo, provides…
Geometry and Topology Seminar: Arunima Bhattacharya, UNC Chapel Hill, Lagrangian Mean Curvature Equations
SAS 1216In this talk, we will introduce the special Lagrangian and Lagrangian mean curvature type equations. We will derive a priori interior estimates for the Lagrangian mean curvature equation under certain natural restrictions on the Lagrangian angle. As an application, we will use these estimates to solve the Dirichlet problem for the Lagrangian mean curvature equation with continuous boundary data…
Math Department Fall 2023 Meeting
SAS 4201We plan on having the beginning-of-the-semester departmental meeting on Monday, August 28, at 4:15 p.m. in SAS 4201. Dean Lewis Owen will join the meeting in the beginning with welcoming remarks and a short Q&A session. Deidre will follow up with a calendar invite and a detailed agenda shortly. Ice cream will be served before…
Biomathematics Seminar: Gerardo Chowell-Puente, Enhancing epidemic forecasts using multi- scale models: Application to COVID-19 and monkeypox epidemics
ZoomZoom Meeting: https://ncsu.zoom.us/j/93046132033?pwd=dkZiTjlKazgzK2Q3aXJra1g2R1Q0dz09 Meeting ID: 930 4613 2033 Passcode: 075251
Algebra and Combinatorics Seminar: Eric Hanson, NC State, Finite-dimensional algebras and the shard intersection order
SAS 4201Reading’s shard intersection order is a lattice structure on a finite Coxeter group which is weaker than the weak order. This structure also appears in the representation theory of finite-dimensional algebras as the inclusion order on certain subcategories of modules. Algebraically, the cover relations of this lattice are traversed by applying a “reduction operation” associated…
Teaching and Learning Seminar: Molly Fenn, Bevin Maultsby, and Stepan Paul, NC State, Gradescope Workshop
SAS 4201The speakers will talk about how to use Gradescope to streamline the grading process for assignments and exams. No experience with Gradescope is assumed, but the speakers will share tips that will benefit experienced users as well as newbies. Participants will be able to join a demo course to experience Gradescope from both the student…

Algebra and Combinatorics Seminar: Martin Helmer, NC State, Effective Whitney Stratification of Real Algebraic Varieties
SAS 4201We describe an algorithm to compute Whitney stratifications of real algebraic varieties. The basic idea is to first stratify the complexified version of the given real variety using conormal techniques, and then to show that the resulting stratifications admit a description using only real polynomials. This method also extends to stratification problems involving certain basic…
Geometry and Topology Seminar: Mathew Kushelman, NC State, On Liouville’s Theorem for Conformal Maps
SAS 1216A theorem of Liouville asserts that the simplest conformal transformations on Euclidean space---translations, dilations, reflections, and inversions---generate all conformal transformations when the dimension is at least 3. I will describe a new proof of this theorem which is shorter and more elementary than the argument, due to Nevanlinna, found in most modern textbooks.
Applied Math Graduate Student Seminar: Walker Powell, NC State, Quasiglobal Sensitivity Analysis for Computational Fluid Dynamic
SAS 4201Determining the sensitivity of model outputs to input parameters is an important precursor to developing informative parameter studies, building surrogate models, and performing rigorous uncertainty quantification. Determining parameter sensitivities over a range of parameter values, termed global sensitivity analysis, requires many model evaluations sampled over the parameter space, which is intractable for many large-scale computational…

Teaching and Learning Seminar: Sunghwan Byun, NC State College of Education, : Knowledge in Interaction: A Key to Promote Participatory Equity During Whole-Group Discussions
SAS 4201Research shows inequitable participation patterns are pervasive in mathematics classrooms. Thus, an important consideration for mathematics instructors is promoting participation by students with historically marginalized backgrounds. Existing literature often focuses on identifying and countering mathematics instructors’ implicit biases against minoritized students. However, redressing inequitable participation patterns requires changing social practices, looking beyond individual minds. In…
Geometry and Topology Seminar: Keaton Naff, MIT, The prescribed-point area estimates in space forms
SAS 1216We discuss a sharp area estimate for minimal submanifolds that pass through a prescribed point in a geodesic ball in a space form. The estimate in Euclidean space was first conjectured by Alexander, Hoffman, and Osserman in 1974 and proven in full generality by Brendle and Hung in 2017. We will show the sharp area estimate also holds…
