## Linda Cook gave a talk on bounding the average degree of a graph with no subgraph isomorphic to a fixed complete bipartite subgraph or a subdivision of a fixed graph at the Discrete Math Seminar

On March 12, 2024, Linda Cook from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar about bounding the average degree of a graph with no subgraph isomorphic to a fixed complete bipartite graph or a subdivision of a fixed graph by a polynomial function of the size of the complete bipartite graph. The title of her talk was “On polynomial degree-boundedness”.
