SUMMARY:Junho Choe\, Constructions of Counterexamples to the Regularity Conjecture
DESCRIPTION:     Speaker\n\n\nJunho Choe\nKIAS\n\n\n\n\n\n\nCastelnuovo-Mumford regularity\, simply regularity\, is one of the most interesting invariants in projective algebraic geometry\, and the regularity conjecture due to Eisenbud and Goto says that the regularity can be controlled by the degree for any projective variety. But counterexamples to the conjecture have been constructed by some methods. In this talk we review the counterexample constructions including the Rees-like algebra method by McCullough and Peeva and the unprojection method.
