### (Computer) Vision without Sight: Finding, Reading, and Magnifying Text

Seminar | October 1 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

Roberto Manduchi, Professor of Computer Engineering, UC Santa Cruz

Neuroscience Institute, Helen Wills

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 >

### Combinatorics Seminar: Coherence of cellular strings of zonotopes

Seminar | October 1 | 12-1 p.m. | 939 Evans Hall

Thomas McConville, MSRI

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 >

### String-Math Seminar: Motives and conformal rigidity

Seminar | October 1 | 2-3 p.m. | 402 LeConte Hall

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 >

### How to Email a Professor to Get a Positive Response: Workshop

Workshop | October 1 | 2-3 p.m. | 9 Durant Hall

Leah Carroll, Haas Scholars Program Manager/Advisor, Office of Undergraduate Research and Scholarships

Office of Undergraduate Research

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 >

### Design Field Notes: Mike Marzalek

Seminar | October 1 | 4-5 p.m. | 220 Jacobs Hall

Jacobs Institute for Design Innovation

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.

About this talk:

Mike Marzalek (BSEE 1969) gradually lost his hearing over time and twelve years ago got a cochlear implant (CI) .... a bionic ear. At that time Mike was a telecommunications research and development... More >

### The "self-stirred" genome: Bulk and surface dynamics of the chromatin globule

Seminar | October 1 | 4-5 p.m. | 106 Stanley Hall

### 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 >

### Let's Talk About Sex!: A Graduate Student Sexual Education Series

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 >
