SUMMARY:Discrete compressed sensing: lattices and frames (Josiah Park\, Georgia Tech)
DESCRIPTION:Lattice valued vector systems have taken an important role in packing\, coding\, cryptography\, and signal processing problems.  In compressed sensing\, improvements in sparse recovery methods can be reached with an additional  assumption that the signal of  interest is lattice  valued\, as demonstrated by A.  Flinth  and G. Kutyniok. Equiangular  tight  frames are  particular systems  of unit  vectors  with minimal  coherence\,  a measure of how well distributed the vectors are\, and have provable guarantees for recovery of sparse vectors in standard methods.  The determination whether real equiangular tight frames have integer span on a lattice has been given a characterization within two papers by A. Bottcher\, L. Fukshansky\, one with S. R. Garcia\, H. Maharaj and D. Needell.  Here the corresponding question is considered for the complex case and several families are demonstrated to have either integer span on a lattice or not.  In addition\, it is demonstrated that a real Parseval tight frame can have integer span on a lattice if and only if the inner products appearing in the system are rational.  (Collaboration with L. Fukshansky\, D. Needell\, and Y. Xin)

SUMMARY:Mathematics: Pure\, Applied\, A Liberal Art ( Al Erisman\, Seattle Pacific University)
DESCRIPTION:From the view of a pure mathematician\, those working in pure mathematics produce pure knowledge. Whether used or not\, it has a great elegance and value in and of itself. Those in applied mathematics simply pick up what has been done and use it in designing or building things. Number theory is often used to illustrate this\, where work done decades ago in pure mathematics is now central to encryption. \nHowever\, the relationship between pure and applied mathematics is a bit more complicated. New insights drawn from applications have been at the root of interesting new areas and questions in pure mathematics. Fourier analysis\, sparse matrix computation\, and graph theory all demonstrate this. \nSome have argued that\, whether pure or applied\, mathematics is not really needed by the average person. Alfred North Whitehead\, a Harvard mathematician and philosopher\, once stated\, “ideas [from mathematics] are of highly specialized application\, and rarely influence thought.” In other words\, mathematics is a specialized skill\, but not a liberal art. \nUsing examples from n-dimensional linear algebra\, I will show why I believe the areas of pure and applied mathematics are deeply tied\, and that this field does indeed influence thought in areas like understanding relationships and political discourse.

SUMMARY:The Roger-Yang Arc Algebra (Helen Wong\, CMC)
DESCRIPTION:  \nBased on geometric considerations\, J. Roger and T. Yang in 2014 defined a version of the Kauffman bracket skein algebra for punctured surfaces that includes arcs going from puncture to puncture. We’ll provide a brief survey of known results about this arc algebra. In particular\, I’d like to mention a recent algebraic result whose proof uses  “generalized” corner coordinates to describe arcs on a triangulated surface. This is joint work with Han-bom Moon. \n

SUMMARY:GEMS Workshop: Graph Theory\, Part I with Professor Michael Orrison\, from Harvey Mudd College
DESCRIPTION:TOPIC: Graph Theory\, Part I \nOn the surface\, graphs seem to be some of the simplest objects you might encounter in mathematics. After all\, they are made up of just two kinds of parts\, vertices and edges\, and those parts fit together in simple ways. But appearances can be deceiving! In this series of two workshops\, we’ll explore several surprising facts about graphs. Along the way\, we’ll see how graphs arise in a variety of settings\, and how they give rise to many challenging but worthwhile problems. \nWHAT IS GEMS: \nThe Gateway to Exploring Mathematics program (GEMS) is a series of workshops that helps excite the interests and curiosity of young students in mathematics and science \nGEMS meets once a month on a Saturday morning from 10:00 AM to 12:00 PM \nGEMS is designed to reach 8th\, 9th and 10th grade students who have an interest in mathematics and science \nParticipants interact with excellent and award winning faculty\, staff\, students and alumni from each of the seven Claremont Colleges \nSPRING 2019 DATES: \nFebruary 2\, 2019 \nMarch 2\, 2019 \nApril 13\, 2019 \nREGISTRATION: \nTo register for our next event on February 2\, please click on the following link: \nhttps://tinyurl.com/GEMS2019Spring1 \nANY QUESTIONS: \nPlease contact our 2018-2019 GEMS coordinator\, Elsa Harris at Elsa.Harris@cgu.edu
