On the abundance for threefolds in positive characteristic

Over the past decade, the Minimal Model Program (MMP) has been largely established for threefolds over perfect fields of characteristic >3. A central conjecture remaining is the abundance conjecture, which predicts that if (X,B) is a projective log canonical threefold pair over an algebraically closed field of characteristic >3 and KX+B is nef, then KX+B is semiample. In this talk, I will discuss some recent results towards this conjecture.
