Raphael Steiner gave an online talk on finding a subdivision of a fixed directed graph with conditions on the length of a path replacing each edge in a digraph of large dichromatic number at the Virtual Discrete Math Colloquium

On August 31, 2022, Raphael Steiner from the ETH Zürich gave an online at the Virtual Discrete Math Colloquium on the existence of a subdivision of a fixed digraph satisfying constraints on the length of a path replacing each edge in a directed graph of large dichromatic number. The title of his talk was “Congruence-constrained subdivisions in digraphs“.
