Title : Quasimorphisms on the Hamiltonian groups of surfaces and the Hofer metric
Speaker : Michael Khanevsky
Place : Amado 814, Technion
Abstract    

NOTE THE SPECIAL DATE AND TIME!

There are several constructions of quasimorphisms on the Hamiltonian groups of surfaces that were proposed by Gambaudo-Ghys, Polterovich, Py, etc. These constructions are based on topological invariants either of individual orbits or of orbits of finite configurations of points and the quasimorphism computes the average value of these invariants along the surface. We show that many quasimorphisms that arise this way are not Hofer continuous. This allows to show non-equivalence of Hofer's metric and some other metrics on the Hamiltonian group.

Title : Recurrence of planar graph limits
Speaker : Asaf Nachmias (TAU)
Place : Taub 7 (UNUSUAL LOCATION), Technion
Abstract    

What does a random planar triangulation on n vertices looks like? More precisely, what does the local neighbourhood of a fixed vertex in such a triangulation looks like? When n goes to infinity, the resulting object is a random rooted graph called the Uniform Infinite Planar Triangulation (UIPT). Angel, Benjamini and Schramm conjectured that the UIPT and similar objects are recurrent, that is, a simple random walk on the UIPT returns to its starting vertex almost surely. In a joint work with Ori Gurel-Gurevich we prove this conjecture. The proof uses the electrical network theory of random walks and the celebrated Koebe-Andreev-Thurston circle packing theorem. We will give an outline of the proof and explain the connection between the circle packing of a graph and the behaviour of a random walk on that graph.

Title : Asymptotic properties and stability of delay differential equations.
Speaker : Alexander Domoshnitsky (Ariel)
Place : Amado 814, Technion
Abstract    

Delays, arising in nonoscillatory and stable ordinary differential equations, can induce oscillation and instability of their solutions. That is why the traditional direction in the study of nonoscillation and stability of delay equations is to establish a smallness of delay, allowing delay differential equations to preserve these convenient properties of ordinary differential equations with the same coefficients. In this paper, we find cases in which delays, arising in oscillatory and asymptotically unstable ordinary differential equations, induce nonoscillation and stability of delay equations. We demonstrate that, although the ordinary differential equation x"(t)+c(t)x(t)=0 can be oscillating and asymptoticaly unstable, the delay equation x"(t)+a(t)x(t-h(t))-b(t)x(t-g(t))=0, where c(t)=a(t)-b(t), can be nonoscillating and exponentially stable. Results on nonoscillation and exponential stability of delay differential equations are obtained. On the basis of these results on nonoscillation and stability, the new possibilities of non-invasive (non-evasive) control, which allow us to stabilize a motion of single mass point, are proposed. Stabilization of this sort, according to common belief requires damping term in the second order differential equation. Results proposed in this talk refute this delusion.

Whitney Extension Problems:

C^m and Sobolev functions on subsets of R^n

(The 9th Whitney Problems Workshop)

Sunday 29.5.2016 - Thursday 2.6.2016

Technion, Haifa, Israel

    The conference will focus on some of the most vibrant developments in function theory related to the celebrated Whitney extension and trace problems for classes of smooth functions. These include new analytic and geometric methods in the study of differentiable structures on finite sets, extension and trace problems for functions in Sobolev spaces and spaces of generalized smoothness defined on closed subsets of R^n, geometric description of Sobolev extension domains, etc.

    The purpose of the conference is to bring together an international group of experts in the areas of function theory and functional and geometric analysis to report on and discuss recent progress and open problems in the area of Whitney type problems and thus foster interaction and collaboration between researchers in these fields.

SUMMER PROJECTS IN MATHEMATICS AT THE TECHNION

Sunday-Thursday, September 25-30

The Mathematics Department at the Technion is inviting advanced undergraduate students to experience research level mathematics in a week of projects. The projects will be mentored by members, postdocs and graduate students from the department. In each project, a group of 2-4 students will investigate a topic (TBA).
