Explore a comprehensive lecture on semistable reduction presented by Dan Abramovich from Brown University. Delve into the problem of resolving singularities in families of complex varieties, first raised by Mumford in 1973. Examine the semistable reduction conjecture proposed by Karu and Abramovich in 2000, including their proof of weak semistable reduction. Investigate recent advancements in functorial weak semistable reduction through Abramovich's collaboration with Temkin and Wlodarczyk. Analyze the work of Adiprasito, Liu, and Temkin, which provides proof for the semistable reduction conjecture. Gain insights into this complex mathematical topic through this hour-long presentation from the University of Miami.
