IFISC Seminar on Wednesday Sep 14, 2022 at 14:30 Place: IFISC Seminar Room Title: Regional Interaction Networks at the origin of the Neolithic in the Near East Speaker: Juan José Ibáñez and Fiona Pichon, Institución Milá y Fontanals de investigación en Humanidades (IMF), CSIC (Barcelona) Abstract: The Neolithic is the period of Prehistory when villages of farming communities appeared. The transition from nomadic hunter gatherer communities to sedentary farming societies is one of the crucial periods in human history. This shift took place, for the first time, in the Fertile Crescent, between 14,000 and 9,000 years ago. Characterizing the regional cultural interactions is a key element for understanding how the transition to the Neolithic was possible. These interactions can be tracked through the analysis of obsidian trade from SE Anatolia to the rest of the Fertile Crescent. Our previous studies demonstrated that obsidian was transferred through complex networks linking distant Neolithic villages. Using our database of obsidian quantities in archaeological sites, we would like to characterize the interaction networks through time. Modelling the transfer of innovations though the previously characterized networks of interaction and comparing modelling results with the actual rhythms of expansion of innovations in the past could help us to understand how the Neolithic emerged. In fact, we think that the Neolithic could be explain as an emergent phenomenon of a growing network of interaction.

Talk on Wednesday Sep 07, 2022 at 15:00 Place: Classroom 5, Antoni M. Alcover Building (Edificio Postgrado) Title: Air transport through the (statistical physics) looking glass Speaker: Massimiliano Zanin, IFISC (UIB-CSIC) Abstract: Air transport, while being a highly engineered system, is also a complex one, whose dynamics emerges from the interactions between a plethora of heterogeneous elements, and develops over multiple spatial and temporal scales. Statistical physics naturally provides numerous tools for understanding its behaviour, and, not surprisingly, a large number of research works have adopted such view-point in the last decades. In this talk we are going to briefly review some applications, from the description of the global structure of airports through complex network theory, to the study of the dynamics of individual flights and of their interactions.

Master Thesis on Friday Sep 02, 2022 at 16:00 Place: Zoom Seminar Title: Generating functional analysis of Lotka-Volterra equations with Hebbian couplings Speaker: Enrique Rozas García, IFISC Abstract: We study a benchmark model in theoretical ecology for population dynamics, the generalized Lotka-Volterra equations, for the case of random Hebbian couplings. A set of binary traits describes each species in the ecosystem and we assume the interaction between any two species to be stronger the more traits they share. We use the generating functional method to derive an effective process with the same statistical properties as the Lotka-Volterra dynamics. This effective process is then used to study the resulting dynamically evolved communities, the different phases of the system, and the transitions between them. We check the predictions of the theory against numerical simulations. We find that increasing the number of traits leads to reduced community sizes and increases instability.
