The IMSM workshop starts with a welcome reception at 5pm on Sunday, July 14, 2019 and ends at 8pm on July 24, 2019. Location: The IMSM workshop will held in SAS Hall on the campus of North Carolina State University. Objective: expose graduate students in mathematics, statistics, and computational science to challenging and exciting real-world…
A commonly used stochastic model for the derivative and commodity market analysis is the Barndorff-Nielsen and Shephard (BN-S) model. At first, an application of the BN-S model will be presented to find an optimal hedging strategy for the oil commodity from the Bakken, a new region of oil extraction that is benefiting from fracking technology.…
We discuss mathematical modeling and analysis of the incompressible viscous flow at the interface of permeable media. Very recently, a simplified theory with asymptotic modeling and related approximations was extensively developed by to provide physically relevant jump interface conditions for the two- or three-dimensional non-inertial flow at the interface of a permeable medium. The results…
In 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 PDEs, where for each unknown function a certain subset of partial derivatives is prescribed and the values of the unknown functions are prescribed along the corresponding transversal coordinate…
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 are especially designed for the computation of incompressible or low-Mach multiphase flows under strong constraints (large density or viscosity ratios, large surface tension) and with…
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 the movement of a robotic root tip in the soil. The model consists in a controlled differential inclusion with a dissipative, upper semi-continuous right hand…

Dean 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 at 3:30PM in SAS 4104
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 will be provided.
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 three-manifold other than S^3 has a non-trivial SU(2) representation, and this is a strategy for an alternate proof of the three-dimensional Poincare conjecture. We will…
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. Nesterov and A. Nemirovskii to a broader class of convex functions. We show that this structure covers many applications in statistics and machine learning. Then, we develop a…
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 this presentation I will go over the basics, answer questions, and give examples on how to use this HPC resource effectively, and easily. Please join…
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 applying to REUs and applying to graduate schools. We also pair undergrads with graduate student mentors for individual mentoring on classes, research, and other things mathematical.…
