Events
John Darges, NC State, Extreme learning machines for variance-based global sensitivity analysis
SAS 1220Variance-based global sensitivity analysis (GSA) can provide a wealth of information when applied to complex models. A well-known Achilles' heel of this approach is its computational cost which often renders…
Semyon Tsynkov, NC State, Imaging With Synthetic Aperture Radar
ZoomSynthetic aperture radars (SAR) use microwaves to obtain images of the Earth's surface from airplanes or satellites. SAR images can be taken during nighttime and prove insensitive to the clouds…
Albert Chern, UCSD, Geometric approaches to infinite domain problems
ZoomNumerical simulations on infinite domains are challenging. In this talk, we will take geometric approaches to analyze the problems and provide new solutions. One problem we tackle is the perfectly…
Bianchini Stefano, SISSA, ITALY, Properties of mixing BV vector fields
ZoomWe consider the density properties of divergence-free vector fields b in L^1(,BV(^2)) which are ergodic/weakly mixing/strongly mixing: this means that their Regular Lagrangian Flow X_t is an ergodic/weakly mixing/strongly mixing measure preserving map when evaluated…
Sonia Kovalesky Day
SAS Hall LobbyAWM is happy to announce that we will be bringing back our Sonia Kovalevsky (SK) Day event this year, which will take place on Saturday, April 9th from 9:15a-2:00p in…
Gregor Kemper, Technical University of Munich, Distance geometry, algebra and drones
ZoomIs it always possible to reconstruct a point configuration in the plane from the unlabeled set of mutual distances between the points? This and other questions translate to invariant theory…
Harley Hanes, NC State, Sensitivity and Identifiability Analysis of Boundary Penalties in a Galerkin Reduced Order Model.
SAS 1220Galerkin reduced-order models (ROMs) approximate computational fluid simulations by reducing snapshot data to a basis of proper orthogonal decomposition (POD) modes and solving for modal coefficients with ordinary differential equations.…
Yeeka Yau, University of Sydney, Cone Types, Automata and Regular Partitions of Coxeter Groups
SAS 4201Coxeter groups were famously proven to be automatic by Brink and Howlett in 1993 and the automaticity of these groups has been an area of continued interest since. In this…
Robin Neumayer, CMU, USA, Quantitative Faber-Krahn Inequalities and Applications
ZoomAmong all drum heads of a fixed area, a circular drum head produces the vibration of lowest frequency. The general dimensional analogue of this fact is the Faber-Krahn inequality: balls…
Math Honors Presentation Session
ZoomSome of our math honors students are giving talks on their research on Friday, April 15, 2022 at 3 pm. There will be nine 12 - 15 minute talks on…
Francesca Bucci, Università degli Studi di Firenze, Italy, Riccati theory in the realm of PDE’s: state of the art and recent advances in the optimal control of evolution equations with memory
ZoomThe well-posedness of Riccati equations plays a central role in the study of the optimal control problem with quadratic functionals for linear partial differential equations (PDEs). Indeed, it allows the…
RESCHEDULED Thomas J. R. Hughes, University of Texas at Austin, Isogeometric Analysis: Mathematical and Engineering Perspectives
ZoomThe vision of Isogeometric Analysis (IGA) was first presented in a paper published October 1, 2005 . Since then it has become a focus of research within both the fields…
Abhi Chowdhary, NC State, Infinite-dimensional Bayesian inversion for fault slip from surface measurements
SAS 1220Given the inability to directly observe the conditions of a fault line, inversion of parameters describing them has been a subject of practical interest for the past couple of decades.…
