Vortrag in der Reihe: Arbeitsgemeinschaft ANGEWANDTE ANALYSIS The cubic nonlinear Schrodinger equation (NLS) is energy-critical (s_c = 1) with respect to the scaling symmetry, where [...]
Florentin Münch (Universität Potsdam, Germany): Ollivier-Ricci curvature, number of ends, and max flow min cut principle 15:00
Florentin Münch (Universität Pot…
Jan 25 @ 15:00 – 16:00
We prove that graphs with non-negative Ollivier-Ricci curvature have at most two ends. To do so, we employ the max flow min cut theorem for [...]

Jan 25 @ 15:15 – 16:45
We prove that the regular $ntimes n$~square grid of points in the integer lattice $mathbb{Z}^{2}$ cannot be recovered from an arbitrary $n^{2}$-element subset of $mathbb{Z}^{2}$ [...]
