Seminar | October 1 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall
Roberto Manduchi, Professor of Computer Engineering, UC Santa Cruz
Reading is a pervasive activity in our daily life. We read text printed on books and documents, shown on directional signs and advertisement, and displayed on computer and smartphone screens. People who are blind can read text using OCR on their smartphone; those with low vision may magnify onscreen content. But these tasks are not always easy. Reading a document with OCR requires taking a... More >

A cellular string of a polytope is a sequence of faces of the polytope that are stacked on top of each other in a particular direction. The collection of cellular strings, ordered by refinement, forms a poset that is homotopy equivalent to a sphere. Among the set of strings, the subposet of coherent ones is homeomorphic to a sphere. In this talk, I will give an oriented matroid characterization... More >

Dmitry Vaintrob, UC Berkeley
Several deep mathematical and physical results such as Kontsevich's deformation-quantization, Drinfeld's associators, and the Deligne hypothesis are controlled by the vanishing of certain obstruction classes in the theory of differential graded operads. I will talk about a way to obtain such vanishing results, as well as higher-genus analogues, using a weight theory implied by a new motivic point... More >
Workshop | October 1 | 2-3 p.m. | 9 Durant Hall
Do you need to email a professor you've never met before to ask for their help, but you don't know where to start? Have you ever written a long email to a professor, only to receive no response, or not the one you hoped? If so, this workshop is for you! We will discuss how to present yourself professionally over email to faculty and other professionals ... More >

Differential Geometry Seminar: Existence of infinitely many minimal hypersurfaces in closed manifolds
Seminar | October 1 | 3:10-4 p.m. | 939 Evans Hall
Antoine Song, Princeton
In the early 80's, Yau conjectured that in any closed $3$-manifold there should be infinitely many minimal surfaces. I will review previous contributions to the question and present a proof of the conjecture, which builds on min-max methods developed by F. C. Marques and A. Neves. A key step is the construction by min-max theory of a sequence of closed minimal surfaces in a manifold N with... More >
Arithmetic Geometry and Number Theory RTG Seminar: Finiteness of Frobenius traces of a de Rham local system
Seminar | October 1 | 3:10-5 p.m. | 784 Evans Hall
Koji Shimizu, UC Berkeley
Pre-talk: For a Galois representation of a number field arising from a smooth projective variety, the Weil conjecture tells that its Frobenius traces are rational numbers. Fontaine and Mazur conjectured that Galois representations satisfying a local condition (de Rham) arise from geometry and hence have a similar finiteness property of Frobenius traces. In the pretalk, I will explain these... More >

About Design Field Notes:
Each informal talk in this pop-up series brings a design practitioner to a Jacobs Hall teaching studio to share ideas, projects, and practices.

Analysis and PDE Seminar: Construction of unstable quasi-periodic solutions for a system of coupled NLS equations
Seminar | October 1 | 4:10-5 p.m. | 740 Evans Hall
Victor Vilaça Da Rocha, (BCAM, MSRI)
The systems of coupled NLS equations occur in some physical problems, in particular in nonlinear optics (coupling between two optical waveguides, pulses or polarized components…). From the mathematical point of view, the coupling effects can lead to truly nonlinear behaviors, such as the beating effect (solutions with Fourier modes exchanging energy) of Grébert, Paturel and Thomann (2013). In... More >
Workshop | October 1 | 6-7:30 p.m. | 183 Dwinelle Hall
The Graduate Student Wellness Group and the Sexual Health Education Program are partnering up for three sextastic events this October! Topics include (but are not limited to) consent, healthy relationships, safer sex, STIs/HIV, and accessing birth control! Specifically, we will be addressing what healthy relationships look/don't look like, why STIs are on the rise, how to practice safer sex, and... More >
