Network Geometry

Abstract
Nearly 15 years ago we found that real-world networks can be meaningfully mapped into hyperbolic spaces. In these spaces coordinates abstract the popularity and similarity of nodes and determine their connectivity in the observed network. This discovery has attracted a great deal of interest in mathematics, physics, computer science, and biology, giving rise to the emerging field of network geometry.
Applications of this framework include community detection, link prediction, and efficient network navigation or search. In this talk we will provide an overview of network geometry, and its application to single layer systems, multiplexes, and temporal networks.
About the Speaker
Fragkiskos Papadopoulos is an Associate Professor at the Department of Electrical Engineering, Computer Engineering and Informatics at Cyprus University of Technology. He received the Diploma in Electrical and Computer Engineering from the National Technical University of Athens (2002), and the PhD in Electrical Engineering from the University of Southern California (2007).
His research deals with the theory and foundations of complex networks and their real-world applications. Areas of interest include: network geometry, random hyperbolic graphs, network navigation, hyperbolic network embeddings, temporal networks, and multiplex networks.

About the EuroCC-2 project
EuroCC 2 will work to identify and address the skills gaps in the European High Performance Computing (HPC) ecosystem and coordinate cooperation across Europe to ensure a consistent skills base.
The role of EuroCC 2 is to establish and run a network of more than 30 NCCs across the EuroHPC Participating States. The NCCs act as single points of access in each country between stakeholders and national and EuroHPC systems. They operate on a regional and national level to liaise with local communities, in particular SMEs, map HPC competencies and facilitate access to European HPC resources for users from the private and public sector.
EuroCC 2 delivers training, interacts with industry, develops competence mapping and communication materials and activities, and supports the adoption of HPC services in other related fields, such as quantum computing, artificial intelligence (AI), high performance data analytics (HPDA) to expand the HPC user base.
This project has received funding from the European High-Performance Computing Joint Undertaking (JU) under grant agreement No 101101903. The JU receives support from the European Union’s programme Digital Europe and Germany, Bulgaria, Austria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Greece, Hungary, Ireland, Italy, Lithuania, Latvia, Poland, Portugal, Romania, Slovenia, Spain, Sweden, France, Netherlands, Belgium, Luxembourg , Slovakia, Norway, Switzerland, Turkey, the Republic of North Macedonia, Iceland, Montenegro and Serbia.
