SUMMARY:Seminario de investigación | Optimization Strategies for the Inverse Eigenvector Centrality Problem: An Application to the Political Blogosphere
DESCRIPTION:Seminario de investigación \nOptimization Strategies for the Inverse Eigenvector Centrality Problem: An Application to the Political Blogosphere \nExpositor | Fabio Raciti | University of Catania \nThe study of complex networks provides fundamental tools for understanding interactions across diverse systems\, from infrastructure to social dynamics. Central to this field are centrality measures\, which quantify the influence of nodes within a given topology. Traditionally\, research focuses on the forward problem: calculating centrality based on a fixed adjacency matrix. However\, many modern applications demand the Inverse Centrality Problem: modifying edge weights so that the network yields a pre-defined centrality vector.\nIn this talk\, we explore various optimization criteria for the Inverse Eigenvector Centrality Problem\, focusing on how different reweightings can achieve global influence targets. Finally\, we apply our methodology to a classic real-world case: the network of US political blogs during the 2004 presidential election. We demonstrate how our optimization strategies perform in a deeply polarized environment\, offering insights into the robustness and manipulability of political discourse. \nSobre el expositor \nFabio Raciti is an Associate Professor of Operations Research at the University of Catania\, Italy\, and has obtained the Italian National Scientific Qualification for Full Professor in Operations Research. \nHis main research interests include inverse problems\, Nash equilibrium problems\, variational inequalities in probability spaces\, network games\, and optimization methods for network centrality measures. \nHe is the author or co-author of more than 75 research papers and of the research monograph Uncertainty Quantification in Variational Inequalities: Theory\, Numerics\, and Applications\, published by CRC Press in 2021. \n  \n

SUMMARY:Seminario | Pensamiento y obra de Raúl Prebisch: debates e interpretaciones a 40 años de su fallecimiento
DESCRIPTION:A cuarenta años del fallecimiento de Raúl Prebisch\, uno de los pensadores económicos más influyentes de América Latina\, el Área de Estudios de la Historia del Pensamiento Económico Latinoamericano del Centro de Estudios de Historia Económica Argentina y Latinoamericana (CEHEAL)\, asociado al Instituto Interdisciplinario de Economía Política (IIEP UBA-CONICET)\, convoca al seminario “Pensamiento y obra de Raúl Prebisch: debates e interpretaciones a 40 años de su fallecimiento”. \nEste ciclo de conferencias rinde homenaje a la trayectoria intelectual y al legado teórico de Prebisch a través de tres sesiones dedicadas a explorar su rol como funcionario\, como teórico y como docente. A lo largo de las jornadas\, se revisitarán sus contribuciones al pensamiento económico latinoamericano\, su visión sobre el desarrollo\, la estructura productiva y el sistema centro-periferia. \nEl seminario se desarrollará los días 15 de abril\, 29 de abril y 14 de mayo de 2026\, a las 15 horas (Buenos Aires\, GMT-3). \nInscripción | Es un evento hibrido\, para acceder al link de Microsoft Teams\nhttps://forms.gle/3xhzt7t8i4qwwtUC6 \nPrograma | + \nLugar | FCE-UBA | SUM
