There are two parts to this Problem. The first part is the derivation of the Boltzmann equation from the Newtonian interacting particle systems, and the second part concerns the relation between the Boltzmann equation and the fluid dynamics. Both involves some form of averaging. The derivation of the Boltzmann equation is both philosophically and mathematically challenging and is historically important. For instance, it is not clear how the probabilistic element comes in and the scaling involved in the averaging is very subtle. The relation between the Boltzmann equation and the fluid dynamics is a rich subject; the Boltzmann equation is known to be able to explain observed phenomena that the traditional fluid equations such as Navier-Stokes cannot. We will discuss these topics, survey the recent progresses and raise open problems.

Moreover, extra care has to be exercised in dealing with nonlinear, high-order, or stiff PDE systems. This minisymposium will focus on recent advances on a variety of time integration methods, such as operator splitting methods, integration factor methods, and alternating direction implicit methods. It intends to create a forum for researchers from different fields to discuss on challenging issues such as the stability improvement via by implicitly treating some subsystems, the computation efficiency of implicit schemes in multi-dimensions, and the spatial treatment of irregular domains/boundaries. Emphasis will be placed not only on computational algorithms and analysis, but also on their applications to emerging physical, engineering, and biological problems.

Mathematically, such problems come in different contexts while sharing the common feature that a cause for an observed effect needs to be determined. In recent years, a subtle link between coefficient recovery of PDEs and control theoretic concepts such as controlability has been established.

It deals with the problem of finding predictive functions based on data. As modern technologies allows to collect data much easier, big data processing and high dimensional data analysis becomes central to knowledge discovery and play essential roles in many fields of modern sciences. This has driven a lot of research in the context of variable selection, dimension reduction, and online learning. In this symposium, we would like to take this opportunities to exchange research ideas, report current advances, and discuss existing challenges in statistical learning theory.

During the last twenty years, quite a few high order variational models have been proposed to fulfill even more advanced imaging tasks. In these models, curvature of curves or surfaces was often incorporated to constitute an appropriate regularizer, which makes these models very intractable numerically. The aim of this minisymposium is to provide a forum to stimulate discussions and establish collaborations for further developments in both the modeling and numerical methods of variational models, especially curvature based ones, in mathematical imaging.

In the case of the Tianhe-2, 3.12 million cores require networking. In 2019 when Exascale systems emerge, more than 100 million cores will need to be connected and the traditional intuition with simple networks will unlikely survive to produce scalable systems. To advance, we must leverage on the, active and young, graph theory, conceptually and computationally, to seek for new breakthrough in network topologies and routing protocols. For a regular graph of N vertices each with k edges, we note it as Nkk , e.g., for a regular graph with N=32 vertices each with k=5 edges, we note it as 32k5. After discovering a series of perfectly optimized (in terms of the graph diameter and average vertex-vertex edge distances) regular graphs with N=4,8,16,32 for the appropriate corresponding node degrees we embed them to generate much larger composite hierarchical graphs, e.g., 16k4$\otimes$32k5 or 8k3$\otimes$16k4 $\otimes$32k5. These embedded graphs, with tens of thousands of vertices, are used to design supercomputer interconnection networks. With the metrics we introduced to measure the network-performance-relevant properties of graphs, we compare our quasi-optimal embedded graphs with many widely adopted networks for supercomputers.

Most common causes are vibrations induced by the moving flow of a gas (air, liquid) which is interacting with a structure. Typical examples include: turbulent jets, vibrating bridges, oscillating facial palate in the onset of apnea. The intensity of the flutter depends heavily on the speed of the flow (subsonic, transonic or supersonic regimes). Thus, reduction or attenuation of flutter is one of the key problems in aeroelasticity with application to a variety of fields including aerospace engineering, structural engineering, medicine and life sciences. Mathematical models describing this phenomenon involve coupled systems of partial differential equations (Euler Equation and nonlinear plate equation) with interaction at the interface - which is the boundary surface of the structure. The aim of this talk is to present a mathematical theory describing: (1) qualitative properties of the resulting dynamical systems (existence, uniqueness and robustness of weak solutions), (2) asymptotic stability and associated long time behavior that includes the study of global attractors, (3) feedback control strategies aiming at the elimination or attenuation of the flutter. Since the properties of the flutter depend heavily on the speed of the flow (subsonic, transonic or supersonic), it is natural that the resulting mathematical theories will be very different in the subsonic and supersonic regimes. In fact, supersonic flows are known for depleting ellipticity from the corresponding static model. Thus, both wellposedness of finite energy solutions and long time behavior of the model have been open questions in the literature. The results presented include: (1) Existence, uniqueness and Hadamard wellposedness of finite energy solutions; (2) Existence of global and finite dimensional attracting sets for the elastic structure in the {absence of any mechanical dissipation}; (3) Strong convergence to multiple equilibria for the subsonic model subjected to a frictional damping imposed on the structure. As a consequence, one concludes that the supersonic flow alone (without any dissipation added to the elastic structure) provides some stabilizing effect on the plate by reducing asymptotically its dynamics to a finite dimensional structure. However, the resulting "dynamical system" may be exhibiting a chaotic behavior. In the subsonic case, instead, a feedback control which provides a sufficient damping of the structure eliminates asymptotically the flutter. Irene Lasiecka, University of Memphis Chair: Carmeliza Navasca, University of Alabama at Birmingham Heritage Hall 102 9:00 AM - 10:00 AM IP4: Hybrid Constrained Iterative Methods for Inverse Problems Linear systems that arise in large scale inverse problems are very challenging to solve. In addition to the problem being large scale, the underlying mathematical model is often ill-posed, which results in highly ill-conditioned coefficient matrices. Noise and other errors in the measured data can be highly magnified in computed solutions. Regularization methods are often used to overcome this difficulty. In this talk we describe hybrid regularization approaches, which combine matrix factorization methods with iterative solvers that can be efficient for large scale problems. Applications from image processing will be used to illustrate the effectiveness of hybrid methods.
