Julian and Markus bring their topics to Sichtbar Hörbar: water, sound, climate crisis, podcasts, sociomateriality. In this episode, the two doctoral students talk about their scientific approaches, their first teaching experiences, and what happens when you suddenly find yourself not just thinking about sociology, but right in the middle of it.

A new paper titled “Greedy Algorithms for Shortcut Sets and Hopsets” has been published on arXiv. The authors are Ben Bals, Joakim Blikstad, Greg Bodwin, Daniel Dadush, Sebastian Forster, and Yasamin Nazari.

The talk focused on recent advancements in extending classical dimension reduction techniques such as the Johnson-Lindenstrauss Lemma and Multidimensional Scaling to more general settings beyond Euclidean geometry. Chengyuan Deng presented new results addressing symmetric and reflexive dissimilarity measures, including non-metric cases, and discussed open research directions in this emerging area.
