Allison Arzeno UCD '09 featured in Geekwire

In December 2022, Geekwire featured an article on Allison Arzeno (formerly O'Hair) under the title "Meet Allison Arzeno, the data science whiz leading insurance tech company Assurance IQ." Allison, who graduated with a major in Mathematics from UC Davis in 2009, had recently been promoted to chief executive officer of Seattle's Assurance IQ, a subsidiary of Prudential Financial, Inc.

Geekwire is a technology news website primarily focused on the area around Seattle, Washington, where Assurance IQ is located. It is an honor for Allison to be featured in this way. During her time at UC Davis, Allison wrote a dissertation under Jesús DeLoera entitled "The Geometric Structure of Spanning Trees and Applications to Multiobjective Optimization." Allison's skilled use of mathematics in the real world makes us proud and provides an example (and a contact) for math majors who wish to follow in her footsteps!

New Books By Our Faculty
Two books authored by our faculty were recently published. In 2021, Roger J-B Wets and his co-author Johannes O. Royset published "An Optimization Primer" as part of the Springer Series in Operations Research and Financial Engineering. The book is described as a richly illustrated book that introduces the subject of optimization to a broad audience with a balanced treatment of theory, models and algorithms and as an accessible onramp to variational analysis with many interesting and timely worked examples. Roger's book is freely available as an ebook through California Digital Library.

More recently, Dan Romik published his "Topics in Complex Analysis." This book, hot off the press, reveals a panoramic vision showing how complex analysis underlies and illuminates phenomena in algebra, number theory, and geometry. The final chapter provides a detailed account of the solution to the sphere packing problem in dimension 8, for which Maryna Viazovska was awarded the Fields Medal in 2022. One notable feature of Dan’s book is that the ebook version is fully open access (provided by the publisher, De Gruyter, and paid for by University funds).

We appreciate these contributions highlighting the beauty of mathematics!

Two successful conferences wrapped up in Summer '23

This July, our Department hosted two conferences! Both were part of annual traditions, namely the Trisectors workshops and the Formal Power Series and Algebraic Combinatorics (FPSAC) annual meetings.

The Trisectors Workshop took place June 26-June 30 and was organized by Alex Zupan, Laura Starkston, Jeffrey Meier, Maggie Miller, and Gabe Islambouli. This year's workshop emphasized connections with symplectic topology. It was preceded by introductory lectures delivered over Zoom during the week leading up to the conference and featured several afternoon devoted to group projects.

The FPSAC meeting, a much larger event, took place July 17-21 and was organized by a much longer list of people including several from UC Davis: Monica Vazirani, Matt Silver, Anne Schilling, Dan Romik, Alex McDonough, Gladis Lopez, Fu Liu, Shelby Kustak, Sean Griffin, Tina Denena, Jesus DeLoera, and Eric Carlsson.

Both conferences were reported to be very successful! Let's thank our colleagues and staff for their hard work!

Elena Fuchs' work discussed in Quanta magazine
What sort of collections of circles fit into a larger circle without overlapping? This question has motivated mathematicians for millenia. Here at UC Davis, Elena Fuchs has studied Apollonian circle packings and found that the curvatures appearing in such families of circles exhibit certain combinatorial features. Her results have led to stronger conjectures, widely accepted among number theorists, but one of these conjectures turned out to be false. This was discovered (via extensive number crunching) during a summer research project involving two students (one graduate, one undergraduate) led by Katherine Stange at the University of Colorado in Boulder. An article in Quanta magazine tells the story of the students' discovery and provides mathematical details.
