- Description:
- We present a geometrically exact equilibrium theory for elastic structures that have in common that they are effectively described by a 1D elastic theory (i.e., an ODE). Apart from the elastic rod this includes higher-dimensional structures such as thin sheets, strips and braids that deform subject to kinematic constraints that can be eliminated...

- Description:
- Many nonlinear systems of partial differential equations have a striking phenomenon of spontaneous formation of singularities in a finite time (blow up). Blow up is often accompanied by a dramatic contraction of the spatial extent of solution, which is called by collapse. A collapse in a nonlinear Schrodinger equation (NLSE) describes the self-f...

- Description:
- Consider electrostatic plasmas described by 1D Vlasov-Poisson with a fixed ion background. In 1946, Landau discovered the linear decay of electric field near a stable homogeneous state. The nonlinear Landau damping was recently proved for analytic perturbations by Villani and Mouhot, but for general perturbations the problem is still largely ope...

- Description:
- Weakly conducting dielectric solid particles and liquid droplets in strong electric fields are known to undergo symmetry-breaking bifurcations leading to steady electrorotation. This so-called Quincke effect, which results from the antiparallel electrostatic dipole induced by the applied field inside the particles, is well described by the class...

- Functions whose values are unbounded linear operators describe a large number of processes in optics. The applications include photonic crystals with material properties of Drude-Lorentz type and computations of scattering resonances.In this talk we present new enclosures of the numerical range of an operator functions T. Contrary to the numeric...

- The nonlinear and stochastic dynamics of oscillating microcantilevers in the Atomic Force Microscope (AFM) are closely linked to the microscope's stability, resolution, minimum force detection, and the ability to generate material contrast. The bifurcations, stability, higher harmonics, and chaotic dynamics mechanisms are now well understood for...

- Description:
- This talk is concerned with optimizing nonlinear functions over the lattice points in a polyhedral set. We present three families of polynomial time algorithms for special cases of the general problem. Each such algorithm makes use of combinatorial, geometric or algebraic properties of the underlying problem. The first problem deals with optimiz...

Taking for granted mathematical issues...

- Description:
- We consider a class of nonconvex quadratic optimization problems having one or two quadratic constraints (1QCQP or 2QCQP). The motivation of this work comes primarily from binary classification in machine learning, but the problems themselves are important; some types of 1QCQP and 2QCQP are well-studied as the trust-region subproblem (TRS) and C...

- Given a finite group G, let C(G) be the set of all cosets of all proper subgroups of G, ordered by inclusion. In joint work with Russ Woodroofe, we show that the order complex of C(G) is not acyclic in characteristic two, and therefore not contractible. This answers a question of K. S. Brown. Our proof uses P. A. Smith Theory and the Classificat...

- Description:
- In economic theory one typically discounts future benefits at aconstant rate. An example of this is the celebrated model of endogeneousgrowth, originating with Ramsey (1928), which leads to the so-called goldenrule in macroeconomics. There are now excellent reasons (intergenerationalequity, for instance) to use non-constant discount rates. There...

The majority of global attractor theory assumes that the equation in question is dissipative, but recent work has shown that similar results can be obtained for non-dissipative reaction-di...
