Abstract
We prove that there exists a function such that for any positive integer , if is a strongly -connected tournament with minimum out-degree at least , then is -linked. This makes progress towards resolving a conjecture of Pokrovskiy. Along the way, we show that a tournament with sufficiently large minimum out-degree contains a subdivision of a complete directed graph. This result may be of independent interest.
