”Finitely presented random groups are surface-like” Goulnara Arzhantseva

Because of the optimized electric field, an effective voltage distribution on the beam axis has been achieved, which performs the required energy gain per gap (see Fig.. A

Here we show by a combination of angle-resolved photoemission (ARPES), scanning tunneling microscopy (STM), and atomic force microscopy (AFM) that the protection mechanism of

One case of particular interest that satisfies the relative rigidity requirement is that of a one-ended, finitely presented group whose two-ended JSJ decomposition has free groups

Abstract: We study quasi-isometric invariants of Gromov hyperbolic spaces, fo- cussing on the ` p -cohomology and closely related invariants such as the confor- mal dimension and

Abstract: It is clear that Gromov boundary ∂(G ∗ H ) of the free product of hyper- bolic groups G and H is, up to homeomorphism, some combination of the topolog- ical spaces ∂G

The talk is based on joint works with Cornelia Drutu (on the Rapid Decay property of such groups) and with Damian Osajda (on the Haagerup property of those

We discuss various (still open) questions on approximation of infinite discrete groups.. We focus on finite-dimensional approximations such as residual finiteness
