On February 8, 2022, Pascal Gollin from the IBS Discrete Mathematics Group gave a talk at the Discrete Math Seminar on the unified Erdős-Pósa type theorem for cycles in graphs whose edges are labelled by multiple abelian groups. The title of his talk was “A unified Erdős-Pósa theorem for cycles in graphs labelled by multiple abelian groups“.

## Pascal Gollin has been appointed as the Young Scientist Fellow (YSF) of IBS

Pascal Gollin from the IBS Discrete Mathematics Group has been appointed as the IBS Young Scientist Fellow as of August 1, 2021. The title of his research proposal was “*Structural questions for infinite graphs, digraphs, and matroids*“. Congratulations!

## 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“.

## Pascal Gollin gave a talk on variants of Woodall’s conjecture at the Discrete Math Seminar

On April 7, 2020, Pascal Gollin presented his work on the relation between the packing of edge sets intersecting all directed cuts in some class B and the maximum size of a minimal nonempty directed cut in B, motivated by Woodall’s conjecture. The title of his talk is “Disjoint dijoins for classes of dibonds in finite and infinite digraphs“.

## Pascal Gollin gave a talk on the existence of a decomposition of an infinite graph into spanning trees at the discrete math seminar

On October 29, 2019, Pascal Gollin from IBS discrete mathematics group gave a talk on the existence of a decomposition of an infinite graph into spanning trees in terms of the existence of packing and covering of spanning trees at the discrete math seminar. The title of his talk was “A Cantor-Bernstein-type theorem for spanning trees in infinite graphs“.

## Welcome Pascal Gollin, a new research fellow in the IBS discrete mathematics group

The IBS discrete mathematics group welcomes Dr. Pascal Gollin, a new research fellow at the IBS discrete mathematics group from October 1, 2019.
