# Pascal Gollin gave a talk on extending a vertex-flame to a large vertex-flame in a countable digraph at the Discrete Math Seminar

On May 18, 2021, Pascal Gollin from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on the existence of a large flame extending a given vertex-flame in a countable digraph. The title of his talk was “Enlarging vertex-flames in countable digraphs“.
