Irina Kogan, NC State, A Generalization of an Integrability Theorem of Darboux
SAS 4201In his monograph “Systèmes Orthogonaux” (Leçons sur les systèmes orthogonaux et les coordonnées curvilignes, Gauthier-Villars, Paris, 1910), Darboux stated three theorems providing local existence and uniqueness of solutions to first order systems of…
Philippe Angot, Aix-Marseille Universite, Recent advances on vector penalty-projection methods for low-Mach multiphase flows with strong stresses and open boundary conditions
We discuss the efficiency of recent advances on the vector penalty-projection methods including the kinematic version which uses fast discrete Helmholtz-Hodge decompositions on edge-based generalized MAC-type unstructured meshes. These methods…
Differential Equations and Nonlinear Analysis Seminar: Michele Palladino, GSSI, Italy, Modeling the root growth: an optimal control approach
In this talk we will propose a new framework to model control systems in which a dynamic friction occurs. In particular, such a framework is motivated by the study of…

Mathematics Departmental Meeting
SAS 1102Dean Chris McGahan will join us for the first 30 minutes of our meeting and will hold a Q&A session There will an ice cream served before the meeting starting…
Introduction to SIAM
The SIAM student chapter will be hosting an introductory lecture aimed at Undergraduates and Graduate students on national SIAM events, SIAM resources, and upcoming student chapter events. Cookies and coffee…
Tye Lidman, NC State, Homology three-spheres and SU(2) representations
One way to effectively show a group is non-trivial is to find a non-trivial representation. A major open question in low-dimensional topology is whether the fundamental group of a closed…
Quoc Tran-Dinh, UNC-Chapel Hill Dept. of Statistics and Operations Research, Smooth Structures in Convex Functions and Applications to Proximal-Based Methods
In this talk, we demonstrate one way of exploiting smooth structures hidden in convex functions to develop optimization algorithms. Our key idea is to generalize a powerful concept so-called "self-concordance" introduced by Y.…
Kirk Main, Let’s Talk IT: HPC Cluster
The High Powered Computing Cluster is a great resource available to all Mathematics staff, faculty, and graduate students. Unfortunately, it is underutilized due to the fairly technical use standards. In…
AWM Ice Cream Social / Welcome Back
SAS 4104Undergrads Union Grads Meeting
The UUG program provides free mentoring for undergraduates in the math program here at NC State. We will hold several seminars and panels throughout the semester on subjects such as…
Cynthia Vinzant, NC State, Solving Cubics with Paper and Turtles
SAS 2102What is the mathematics behind origami? What can be achieved by just folding paper? We'll talk about the beautiful geometry underlying these questions and more, including a classical algorithm for…
Applying for Graduate Research Fellowships
Speaker: Seth Sullivant This presentation will explain the ins and outs of applying for graduate research fellowships, with special emphasis on the NSF graduate research fellowship.
Corey Jones, Ohio State University, Vanishing of categorical obstructions for permutation orbifolds
Modular tensor categories are rich mathematical structures. They are important in the study of 2D conformal field theory, arising as categories of modules for rational vertex operator algebras. The orbifold construction A-> A^{G} …
Sherry Gong, UCLA, On the Kronheimer-Mrowka concordance invariant
We will talk about Kronheimer and Mrowka’s knot concordance invariant, $s^\sharp$. We compute the invariant for various knots. Our computations reveal some unexpected phenomena, including that $s^\sharp$ differs from Rasmussen's…

SAS 4104Differential Equations and Nonlinear Analysis Seminar: Kazufumi Ito, NC State, Optimal control of sate constrained PDEs system with Spars controls
In this talk we discuss a point-wise state constraint problem for a general class of PDEs optimal control problems and sparsity optimization. We use the penalty formulation and derive the necessary…
