Madeleine Weinstein (University of California, Berkeley), Emil Horobet (Târgu-Mureş – Sapientia Hungarian University of Transylvania): Offset hypersurfaces and persistent homology of algebraic varieties 10:00
Jan 23 @ 10:00 – 11:00
In this talk we present connections between the true persistent homology of algebraic varieties and their corresponding offset hypersurfaces. By Hardt’s theorem, true persistent homology [...]

Jan 23 @ 15:15 – 16:15
On a class of closed oriented Riemannian manifolds with lower bounds on Ricci curvature and injectivity radius we study the parameter given by a characteristic [...]

Volker Betz (TU Darmstadt): Long cycles in Spatial Random Permutations. Main challenges and some results 16:45
Jan 23 @ 16:45 – 18:15
Vortrag in der Reihe: Oberseminar ANALYSIS – PROBABILITY I will introduce the model of spatial random permutations and talk about its connection to quantum physics, [...]
Haitian Yue (University of Massachusetts): Well-posedness for the cubic NLS on tori 14:15
Jan 25 @ 14:15 – 15:45
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
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 [...]
Michael Dymond (Innsbruck): Mapping $n$ grid points onto a square forces an arbitrarily large Lipschitz constant. 15:15
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 $mathbb{Z}^{2}$ [...]
Christian Rose (TU Chemnitz, Germany): Heat kernels and integral Ricci curvature bounds 16:15
Jan 25 @ 16:15 – 17:15
Gaussian heat kernel bounds play a fundamental role in geometric analysis. We present recent results on explicit Gaussian upper bounds for non-compact manifolds depending on [...]
Sebastian Riedel, (TU Berlin): to be announced 11:00
Jan 26 @ 11:00 – 12:30
Vortrag in der Reihe: Arbeitsgemeinschaft ANGEWANDTE ANALYSIS
Nils Bruin (Simon Fraser University, Burnaby): Determining the rational points on curves 10:00
Jan 29 @ 10:00 – 11:00
Some of the oldest problems in mathematics amount to finding solutions in rational numbers to equations describing curves. Faltings established the landmark result that curves [...]
Vladimir Shikhman (Technische Universität Chemnitz): Power method tâtonnements for Cobb-Douglas economies 16:00
Jan 29 @ 16:00 – 17:00
Abstract. We consider an economy with consumers maximizing Cobb-Douglas utilities from the algorithmic perspective. It is known that in this case finding equilibrium prices reduces [...]
Jonathan Zachhuber (Johann Wolfgang Goethe-Universität): Counting Flat Surfaces with many Symmetries 10:00
Jan 30 @ 10:00 – 11:00
A flat surface is a polygon in the plane where we have identified parallel sides or equivalently a complex curve together with a choice of [...]

Jan 30 @ 15:15 – 16:45
Vortrag in der Reihe: Oberseminar ANALYSIS – PROBABILITY We consider level set percolation for the Gaussian free field on the Euclidean lattice in dimensions larger [...]
Christian Seis (Universität Münster): A quantiative approach to the DiPerna–Lions theory for transport equations 16:45
Jan 30 @ 16:45 – 18:15
Vortrag in der Reihe: Oberseminar ANALYSIS – PROBABILITY In their celebrated theory of renormalized solutions, DiPerna and Lions (1989) establish well-posedness and stability properties for [...]
