If you must have a expresso in the morning, we recommend Mishka's Cafe (downtown 2nd st. and E), but there are other coffee shops in downtown, e.g., Peet's coffee (E st), Starbucks (F st), Delta Venus (B st). The excellent Davis farmer market (B and 3rd) has sweet breads and coffees too The lunch organized by the conference is a buffet lunch at the residence hall dining hall (5 mins walk from the conference site). Lunch needs to be purchased in advanced (via registration!). The lunch is all-you-can-eat style buffet, with several food stations that include typical fair such as sandwiches, soups & salads, pizzas, burgers, as well as special gluten-free, vegetarian, or vegan choices. Free unlimited soft drink, coffee, tea, and dessert and fruit are included. NOTE: It takes 10-15 mins to walk to other lunch options in downtown Davis.
We very much hope people will stay until the end of the event and have a chance to socialize with old and new friends and colleagues. Here below are some options for dinner that take large groups (last two are great choices but are outside downtown Davis). We suggest to call ahead and make a reservation if your group is large. The entire list of restaurants in Davis can be found at all Davis dining options. [davisdowntown.com] - Sophia's Thai Kitchen (530) 758-4333
- Burgers and Brew (530) 750-3600
- Woodstock's Pizza Davis (530) 757-2525
- Steve's Pizza (530) 758-2800
- Sudwerk Brewery and Restaurant (530) 758-8700
- Symposium Restaurant & Pizza (530) 756-3850
When we add numbers in the usual way, "carries" occur (for two digits chosen at random, the chance of a carry is 45%). We can do better, by a factor of two, by using signed digits but no choice of digits does any better. This last result is a theorem in additive combinatorics. The same kind of questions can be asked for any group (as I will explain, carries are co-cycles). With Shao and Soundararajan, we proved the following: let H be a normal subgroup of a finite group G. Let X be co-set representatives for H in G. Let C(X)=\#\{x,y in X with xy outside X}/|X|^2 (so C(X) is, at most, 1). We show that if C(X) is greater than 7/9, the extension splits (there is a choice of coset representatives with no carries).
One of the corner stones of extremal combinatorics is the 1907 result of Mantel that a triangle free graph on n vertices cannot have more than half the maximum possible number of edges as n goes to infinity. The more detailed version of this question asks what the edge density will limit to given a specific triangle density. The full answer to this question eluded mathematicians for almost 100 years until it was settled by Razborov around 2007 using a framework called flag algebras. This tool has led to several other powerful results in extremal combinatorics. In this talk I will present a new take on this approach and its offshoots using symmetry exploiting methods in optimization. Along the way one encounters algebra, combinatorics, probability, representation theory, and optimization, making for a wild ride across several mathematical landscapes. Joint work with Annie Raymond and Mohit Singh.
The talk will be an elaboration on the principle that a mixture of randomness and order makes life interesting. A common lie heard from mathematicians is a variation of: "The talk will be understandable by general audience." I will take that statement as a challenge, presenting ideas such as self-organization and metastability with no formal statements at all, in fact with no mathematical symbols.
Eigenvectors of square matrices are central to linear algebra. Eigenvectors of tensors are a natural generalization. The spectral theory of tensors was pioneered by Lim and Qi a decade ago, and it has found numerous applications. We discuss the use of orthogonal tensor decompositions in data analysis, and we present work with Abo and Seigal aimed at characterizing which configurations of vectors arise as the eigenvectors of some tensor. This lecture also serves an invitation to applied algebraic geometry.
Knot theory is the study of embeddings of simple closed curves in three-dimensional space. A natural extension of knot theory is the study of embeddings of graphs. However, in contrast with knots, the structure of a graph can be complex, and this can affect all of its embeddings. If every embedding of a graph has a particular property, then we say that property is intrinsic to the graph. For example, a graph is said to be intrinsically knotted if every embedding of the graph in space contains a knot. In this talk, I will discuss intrinsic knotting and other intrinsic properties of graphs. ALL students (undergraduate and graduate) are invited to submit short proposals for posters to be included the Contributed POSTER Session of the Meeting. This session accepts contributions in all areas of mathematics, and all complete proposals will be considered. There are many slots, but space is not unlimited, so please submit your poster early! It will help us plan for easels and boards needed. Submissions should contain a title, an abstract (not to exceed 150 words, suitable for inclusion in the conference program), the name(s) of author(s) of the work (with an indication of who the presenter will be), and any special requests. Do include in each submission the institutional affiliations of all authors. Each poster will be provided an easel space and a board to display the work. Abstracts should be submitted in LaTeX format, with an accompanying PDF file. If you do not use LaTeX, please submit a Text document together with a PDF file. Please email all submissions to Kristen Beck. The submission deadline is Student presenters receive complimentary registration and Saturday luncheon, plus a free one-year membership to the MAA or (to those who are already MAA members) a free book. We looking forward to your submissions! For the first time in the history of the Golden Section, we will be hosting a mathematical art exhibition. If you know anyone who creates art with strong mathematical theme or content, please encourage them to submit their piece for consideration in the exhibit.
For consistency, we will adhere with many of the guidelines set by the Joint Mathematical Meetings art exhibit. Flat works will be limited in size to 28" x 28" (including frame), and 3-D works will be limited to 18" x 18" x 18". Exceptions will occasionally be made for existing artworks that exceed these dimensions. There is a limit of three artworks per artist. An exception is a group of closely-related small pieces that number no more than five pieces occupying a total footprint of no more than 15"x 15", which can be submitted as a single piece. An artist can appear on more than one submission in the case of collaborative work, but the total number of artworks for any given artist is limited to three regardless of whether some are collaborative or not.
Please email at most two photos (<= 10 MB each) of each piece you would like to submit, along with a brief description (< 100 words) of the piece, to Shirley Yap by February 12. Please put ART EXHIBIT in the subject title. A committee will review all submissions for mathematical content and craftsmanship and respond to artiests by February 19.
The art exhibit will take place during an hour and a half between the morning and afternoon sessions. During these time, we encourage the artists to stand or sit by their pieces so as to encourage interaction between the viewers and the artist. Artists are expected to register for and attend the conference. When you arrive at the conference in the morning, you may store your piece in a locked room until the art exhibition begins and retrieve it at the end of the event. Artists are responsible for their pieces. The MAA Golden Section and UC Davis do not assume any responsibility and will only provide storage and display space for the artwork. |
