Title : Surface and grain boundary evolution in thin monocrystalline and polycrystalline films
Speaker : Vadim Derkach
Place : Amado, 814, Technion


Professor Amy Novick-Cohen


If we look at most materials under a microscope, we will see a network of grains and grain boundaries as well as holes, cracks, cavities and additional various defects. These features determine the microstructure of the material, whose properties are crucial in determining the various mechanical, electric, magnetic, and optical properties of the material. The microstructure is in turn influenced by the evolution of the exterior surface via the grain boundaries.

In my lecture I shall report on 3D numerical studies of the motion of quadruple junctions and thermal grooves in thin polycrystalline films where the mean curvature motion of the grain boundaries and the surface diffusion evolution of the exterior surfaces couple along the thermal grooves. Our algorithms could also be used to study hole evolution in thin monocrystalline and polycrystalline films, where only the motion of the exterior surface needs to be considered.

To describe the physical models and their motion, we used a system of partial differential algebraic equations with boundary and initial conditions. Our numerical approach used  a finite difference scheme on a staggered grid with  partially parallelized numerical algorithms, the backward Euler method, and Newton’s method..  Simulations, written in MATLAB and ”C”, were able to indicate some new instabilities.

Abstract: It is a well known question of Gromov whether there exist groups with no fixed point free action on CAT(0) spaces. Gromov conjectured that random groups have this property. In this talk we will present groups that have no fix point free isometric actions on Hadamard manifolds. These are the Steinberg groups defined over the ring R = Fp [t] In the talk we will define the Steinberg groups and show some nice properties regarding to them. We will also describe Hadamard manifolds which are complete simply connected non-positively curved Riemaniann manifolds. In particular we will study fat triangles in these manifolds and show how to deduce fix point properties

Title : On Reduced Horoboundary Actions of Groups and Property (EH)
Speaker : Miel Sharf
Place : Amado, 814, Technion

Supervisor: Associate Professor  Uri Bader

Abstract: We shall study a variant of property (EH) (defined by Bader-Finkelshtein), called weak property (EH), and its relation to triviality of certain reduced horoboundary actions. We will use this property to show that generalized Heisenberg groups act trivially on their horoboundary, both in the discrete and in the smooth case, extending the results of Bader-Finkelshtein.

Place : Amado 814, Technion

Center for Mathematical Sciences

Mostly Markov Mixing

Summer Workshop For Graduate Students

(and Post-Docs and Gutsy Undergrads)

Sunday-Wednesday 30.8.15 - 2.9.15

Followed by: Workshop for Researchers (and Students)

Thursday-Friday 3.9.15 - 4.9.15

Technion, Haifa, Israel

Registration has been extended through August 7th

The workshop will focus on topics connected to and arising from the problem of calculating the mixing rate for Markov processes on large finite state spaces as the size of the state space tends to infinity.
