 2 (Thursday) MATH LECTURE"On two conjectures of Erdos" Oliver Roche-Newton (University of Bristol )11 am, Hylan 1106A We shall discuss the sum-product conjecture and the distinct distance conjecture and connections between the two. 31 (Friday) Analysis SeminarAn Introduction to the Hyperelastic Rod EquationDavid Karapetyan, University of Rochester2 pm - 3 pm, Hylan 1106A In this talk we give an introduction to the history of the hyperelastic rod equation (HR), a "weakly dispersive" perturbation, parametrized by $\gamma \in \mathbb{R}$, of a non-viscous Burgers equation. A notable feature of HR is that it subsumes the Camassa-Holm equation ($\gamma=1$) and the Benjamin-Bona-Mahony equation ($\gamma=0$), but unlike these equations it has an ill-posedness theory which is largely incomplete for $\gamma \neq 0,1$. We also discuss some recent results on the Holder continuity of the data-to-solution map for HR from $H^s$ to $H^r$, where $s>r$.
