Title: Nonlinear dynamics of plant pigmentation Advisor:  Dr. Patrick Shipman Committee:  Dr. Jennifer Mueller, Dr. Mark Bradley, Dr. Richard Finke Red, blue, and purple colors in plants are primarily due to plant pigments called anthocyanins. In a plant cell, an equilibrium is established between anionic and cationic forms of anthocyanins as well electrically neutral colorless […]

Time Integration Methods and Software for Scientific Simulations: Carol S. Woodward Time-dependent systems are at the heart of numerous scientific applications requiring simulation.  While single rate, fixed step size time integration methods have been used for decades, adaptive step methods and schemes that can efficiently evolve problems with multiple time scales have not yet been fully […]

Dear friends of FRAGMENT, to decompress from the adrenaline high weekend of WAGS, we are very happy to have Rob Silversmith, from Warwick/MSRI, speak to us this week (at 3:15pm). Given a bipartite graph G (subject to a simple constraint), the "cross-ratio degree” of G is a non-negative integer invariant of G, defined via a […]

A Potpourri of Projective 2-Designs Emily King Colorado State University   Zauner conjectured that for all $d$ there exists a set of $d^2$ equiangular vectors in $C^d$ (SICs or Gabor equiangular tight frames). Another important open problem concerns the existence of $d+1$ so-called mutually unbiased bases (MUBs) in $C^d$ (maximal sets of MUBs) for any […]

Advisor:  Dr. Rachel Pries Committee:  Dr. Jamie Juul, Dr. Indrajit Ray Title:  GR-NTRU: Understanding the Security of Lattice-based Cryptosystems through Group Rings Originally conceived in 1996 by authors Hoffstein, Pipher, and Silverstein, the Nth-degree Truncated Ring Unit (NTRU) cryptosystem rivals common cryptosystems such as RSA in terms of speed and security. In pursuit of a […]

The Moduli and enumeration seminar (formerly MMARGS) is a weekly reading seminar organized by Maria Gillespie, Renzo Cavalieri and myself.  Participants take turns speaking on topics they find interesting, usually loosely connected to moduli spaces, algebraic curves, and counting problems in algebraic geometry.  If you are interested in attending, please let me know and I […]

The Number Theory Lab will meet weekly on Thursdays at 1pm in Weber 201. Our first talk will be on Thursday, September 1. We will begin this semester with a series of talks “What is …?” introducing various topics in number theory at a beginning graduate student level. We especially encourage the incoming graduate students […]
