Upper bound on coarsening rate
Colloquium| Speaker: | Xiaodong Yan, Courant Institute |
| Location: | 693 Kerr |

Description
Late time coarsening has been observed in epitaxial growth models.
Results from experiments and numerics on isotropic epitaxial growth models
suggest that the characteristic
length scale $L(t)$ grows as $t^{\frac{1}{3}}$ at late times. We prove a
weak one sided version of this statement. Our analysis follows a strategy
introduce by Kohn and Otto in their study of phase transition.
3:45 Refreshments will be served before the talk in 551 Kerr Hall
