Title : The images of non-commutative polynomials evaluated on matrix algebras.
Speaker : Sergey Malev (The University of Edinburgh)
Place : Amado 814, Technion


Let $p$ be a multilinear polynomial in several non-commutingvariables with coefficients in an arbitrary field $K$. Kaplanskyconjectured that for any $n$, the image of $p$ evaluated on theset $M_n(K)$ of $n$ by $n$ matrices is either zero, or the set ofscalar matrices, or the set $sl_n(K)$ of matrices of trace $0$, orall of $M_n(K)$. We prove the conjecture for $K=\mathbb{R}$ orfor quadratically closed field and $n=2$, and give a partial solution for an arbitrary field $K$.We also consider homogeneous and Lie polynomials and providethe classifications for the image sets in these cases.

Title : Homology of Random Simplicial Complexes Based on Steiner Systems
Speaker : Amir Abu-Fraiha
Place : Amado, 814, Technion

Following the work of Linial and Meshulam on random simplicial complexes, we introduce a model for random complexes with bounded degree and study its topology. We use spectral gap theory, in particular, Garland's method, to show homological connectivity of these random complexes. We also show an upper bound on Betti numbers of complexes with highly connected links, in the spiritof Garland's method.

Title : Stability of axisymmetric liquid bridges
Speaker : Leonid Fel
Place : Amado 814, Technion

Based on the Weierstrass representation of second variation, we develop a non-spectral theory of stability for isoperimetric problem with minimizedand constrained two-dimensional functionals of general type and free endpoints allowed to move along two given planar curves.We establish the stability criterion and apply this theory to the axisymmetric liquid bridge between two axisymmetric solid bodies without gravity to determine the stability of menisci with free contactlines.For catenoid and cylinder menisci and different solid shapes, we determinethe stability domain. The other menisci (unduloid, nodoid and sphere) are considered in a simple setup between two plates or two spheres.

Joint work with B. Rubinstein.

Title : Phase-Exchange Thermoacoustics: A unified derivation and stability analysis
Speaker : Daniel Felman-Levy
Place : Amado, 814, Technion

Thermoacoustics is a highly promising technology for the upcoming decades. Based on the heat transfer between a temperature gradient stack and an oscillating acoustic wave, it is expected to replace current heat pumps or heat engines, such as solar panels or air conditioners, due to its improved efficiency compared to conventional methods. However, it is yet a young research topic with many improvements and tests to come. One of the most recent improvements is the addition of a reactive component to the inert media as it creates a coating layer over the stack pore's walls and forms an additional concentration gradient as a result of its phase-exchange interaction with the active component, encouraging the oscillating amplitudes for a more desirable performance and efficiency. This thesis develops the mathematical non-dimensional approach established by the physical parameters of the system building it from the conservation of momentum, concentration and energy equations applying the required boundary conditions to solve for the velocity, concentration and temperature fluctuations, respectively. Then plugging the results into the continuity equation in order to arrive to the wave equation, which describes the pressure fluctuations along the stack. At this point, it is possible to find the acoustic work flux, which determines the efficiency of the system based on all the physical parameters involved. The results evaluation is focused on the analysis of limiting cases and approximations, such as the inviscid limit or the boundary layer approximation, and their theoretic impact on the performance. Finally, the required setup for a concentration and a temperature gradient onset is found independently in the pursuit of triggering an instable oscillation.

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.
