The distance matrix of a tree appears in a range of contexts, from phylogenetics to physical chemistry. I will describe a new result about the spectrum of this matrix, one that gives affirmative answer to two questions about matroid positivity properties. These are both strengthenings of Mason's conjectures about the log-concavity of sequence of numbers of independent sets of a matroid, proposed by Igor Pak and by Giansiracusa, Rincón, Schleis, Ulirsch, respectively.
At the heart is a characterization of the gross substitutes property from economics in terms of the Lorentzian property of a generating function.
This is joint work with Federico Ardila-Mantilla, Sergio Cristancho, Chris Eur, June Huh, and Botong Wang.

Arkeologisk fredagsseminar med professor Dagfinn Skre (KHM). Seminaret baserer seg p? ett av mange delstudier i Skres nyeste bok (2025), The Northern Routes to Kingship. A History of Scandinavia AD 180–550. Med utgangspunkt i Rogaland–H?logaland-forbindelsen skisseres bokens hovedgrep: at det var ankomsten av veteraner fra den romerske h?r som f?rte til det store skiftet i skandinaviske stammesamfunn p? slutten av det 2. ?rhundre e.Kr.?

Juliette Lacherez is a PhD candidate in the Théorie de la Matière Condensée group within Statistical Physics at Université de Bordeaux, working under the supervision of Thomas Salez and Yacine Amarouchène. Her research focuses on numerical approaches to complex physical systems, using simulations as a powerful tool to test theoretical models beyond experimental constraints. She primarily works with Langevin simulations to study nontrivial systems such as active swimmers in confined flows and colloids diffusing near deformable, fluctuating boundaries.

Anders Malthe-S?renssen is a professor of physics. His research interests spans computational and statistical physics, the physics of geological processes, artificial intelligence and neuroscience. He has systematically studied how the frictional behavior of materials may depend on the contact history, for example, by demonstrating that the static coefficient of friction may depend on the acceleration of a block while coming to rest. More recently, he has addressed nano-scale frictional behavior for single contacts, sheets and metamaterials.
