  4. 3. Impact of Central Nodes in Information Propagation over Graphs

    University essay from Lunds universitet/Matematisk statistik

    Author : Oskar Mellegård; [2023]
    Keywords : Mathematics and Statistics;

    Abstract : There are many systems which can be represented as graphs, to say the least the networks in which we communicate with each other. Thorough understanding of graph structures enables better predictions of the dynamics in real life networks, such as the spreading of a disease in a community or failure propagation in a system.
