Cycles of Well-Linked Sets II: an Elementary Bound for the Directed Grid Theorem
Meike Hatzel, Stephan Kreutzer, Marcelo Garlet Milani +1
In 2015, Kawarabayashi and Kreutzer proved the Directed Grid Theorem - the generalisation of the well-known Excluded Grid Theorem to directed graphs - confirming a conjecture by Re…
