A Converse to a Theorem of Gross-Zaqier-Kolyvagin
4:30pm|S-101

The theorem of the title is that if the L-function L(E,s) of an elliptic curve E over the rationals vanishes to order r=0 or 1 at s=1 then the rank of the group of rational rational points of E equals r and the Tate-Shafarevich group of E is finite...

Workshop on Topology: Identifying Order in Complex Systems

Towards a Covariant Theory of Coarsening via Emergent Symmetries
Stephen Watson
4:30pm|David Rittenhouse Laboratory, A8

The scaling symmetries of both static and dynamic critical phenomena naturally yield associated power laws and scaling functions. Going beyond simple scalings, we reveal how general emergent symmetries control the coarsening statistics of non...

Workshop on Topology: Identifying Order in Complex Systems

Properties of Cellular Microstructures: Polycrystals, Foams, and their Idealizations
David Srolovitz
1:30pm|David Rittenhouse Laboratory, 4N12

Cellular structures are compact domains joined along codimension 1 interfaces to fill space. Such cellular microstructures are ubiquitous in materials science and biology. I will briefly review the basic theory of cellular structure evolution via...
