Room 223, Weber building, 4.15pm (i.e. you can arrive at 4pm for free parking) with refreshments at 3:30 in WB117. Michael Levet - UC Boulder Title: Weisfeiler--Leman for Group Isomorphism: Action Compatibility Abstract: The Weisfeiler—Leman (WL) algorithm is a key combinatorial subroutine in Graph Isomorphism, that (for fixed $k \geq 2$) computes an isomorphism invariant […]

Dear friends of FRAGMENT, this week we are very happy to have Giovanni Inchiostro visit us from University of Washington. Seminar lunch at 12noon for the interested (grad students subsidized). See you soon! Consider a quasi-compact moduli space M of pairs (X,D) consisting of a variety X and a divisor D on X. If M […]

We are excited to announce that we will be hosting FRNTD Spring 2022 here at CSU as a special joint Conference with Western Algebraic Geometry Symposium (WAGS) on April 23, 2022.  The talk by Stefan Erickson will be designed with an undergraduate audience in mind, and the other talks will be designed with a graduate […]

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 […]

Snacks Provided!

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 […]
