14:15 RĂ¼diger Schultz (University of Duisburg-Essen):  The right gas in the right place at the right time - and what mathematics has to do with it

This talk is devoted to recent activities in mathematical investigation of critical infrastructures, motivated mainly by pipeline systems for natural gas and to some extent electrical power grids. The planning and operation of these structures typically becomes confronted with (often massive) data uncertainty, for which different modelling approaches arise. The talk proceeds along practical applications and focusses on the mathematical inspiration they induce, from mathematical miniatures to complex resource planning.

15:45 Shankar Venkataramani (University of Arizona): Leaves, flowers, and sea-slugs: From discrete geometry to discrete mechanics

I will talk about some geometric questions that arise in the study of soft/thin objects with negative curvature. After reviewing basic ideas from discrete differential geometry (DDG), I will motivate the need for new "geometric" methods, based on DDG, for studying the mechanics of leaves, flowers, and sea-slugs. I will present some of our results in this direction. This is joint work with Toby Shearman and Ken Yamamoto.
