Expanders and Extractors

Workshop | January 30 – February 3, 2017 every day |  Calvin Laboratory (Simons Institute for the Theory of Computing)

 Simons Institute for the Theory of Computing

This workshop will focus on explicit constructions of graphs and functions with pseudorandom properties. There will be two main themes related to each object in the title. For expanders, these will be proofs of existence of expander graphs using lifts, a la Bilu-Linial and Marcus-Spielman-Srivastava, and the possibility of using the method to obtain explicit constructions of Ramanujan expanders...   More >

Diazo Compounds: Versatile Tools for Chemical Biology

Seminar | January 31 | 11 a.m.-12 p.m. |  Pitzer Auditorium, 120 Latimer Hall

 Prof. Ronald Raines, Department of Biochemistry, University of Wisconsin-Madison

 College of Chemistry

The Huisgen azide−alkyne 1,3-dipolar cycloaddition of azides and alkynes has had a profound impact on chemical biology. The diazo group shares this reactivity with the azido group while conferring additional versatility. A diazo compound can be accessed readily from its parent azide by simple deimidogenation, that is, loss of “NH”, using a phosphine reagent. Cycloaddition with a diazo...   More >

PMB Seminar : "What flat leaves can teach us about developmental reproducibility"

Seminar | January 31 | 11 a.m.-12 p.m. | Energy Biosciences Building, EBB First Floor Conference Room

Seminar 217, Risk Management: Leveraging Herd Behavior in Foreign Exchange Markets

Seminar | January 31 | 11 a.m.-1 p.m. | 639 Evans Hall

 Speaker: Arnav Sheth, Saint Mary's College of California

 Center for Risk Management Research

Abstract: We examine the relationship between equity and foreign exchange markets at, and around, the WM/Reuters benchmark exchange rate known as the the `Fix'. Execution at the Fix is a service offered by brokers (normally banks) provided they obtain the trade order until a certain time prior to 4pm GMT (11 am Eastern Time).

Caring for Dying: The Art of Being Present (BEUHS167)

Workshop | January 31 | 12:10-1:30 p.m. | Tang Center, University Health Services, Section Club

 Michelle Peticolas, PhD

 Be Well at Work - Employee Assistance

In the face of impending death, the caregiver’s needs are often overlooked. Participants will view Dr. Peticolas’ film, Caring for Dying: the art of being present, about the experiences of three individuals who accompanied their dying loved ones. Workshop participants will be invited to share their own stories if they wish. Goals of the workshop include:

• Learning strategies for staying...   More >

Commutative Algebra and Algebraic Geometry: Ring spectra for commutative algebraists

Seminar | January 31 | 2:10-3 p.m. | 939 Evans Hall

 Mengyuan Zhang, UC Berkeley

 Department of Mathematics

We introduce a new category to do commutative algebra in - the stable homotopy category. The talk starts by its construction and properties, with highlights on the comparison with the derived category of abelian groups. We then proceed to examine ring spectra, and generalize (derived) commutative algebra in this new context. Key examples of the talk will be regular ring spectra, gorenstein ring...   More >

Commutative Algebra and Algebraic Geometry: Families of ideals of the same size

Seminar | January 31 | 3:10-4 p.m. | 939 Evans Hall

 Irena Peeva, Cornell University

 Department of Mathematics

The Hilbert function is an invariant that measures the size of a homogeneous ideal. It encodes important information (for example, dimension and degree). Grothendieck introduced the Hilbert scheme that parametrizes subschemes of $P^r$ with a fixed Hilbert polynomial. The main general result about the structure of Hilbert schemes is Hartshorne’s Theorem that the Hilbert scheme is connected. The...   More >

3-Manifold Seminar: Colorings of graphs

Seminar | January 31 | 3:40-5 p.m. | 891 Evans Hall | Canceled


 Department of Mathematics

I'll discuss the question of whether a map on a compact surface has a finite-sheeted covering which is 4 colorable? We can deduce this from a question about automorphism group-invariant probability measures on the space of c-colorings of a graph of chromatic number c. Some related results will be discussed.

Polarons, Polaritons, and the Lead Halide Perovskite Puzzle

Seminar | January 31 | 4-5 p.m. |  Pitzer Auditorium, 120 Latimer Hall

 Prof. Xiaoyang Zhu, Department of Chemistry, Columbia University

 College of Chemistry

The feverish research activity on lead halide perovskites has been fueled by their exceptional optoelectronic properties, e.g., in solar cells and light-emitting devices. Hybrid lead halide perovskites exhibit carrier properties that resemble those of pristine nonpolar semiconductors despite static and dynamic disorder, but how carriers are protected from efficient scattering with charged defects...   More >

This dialogue will explore representation on stage and ways in which traditional casting practices can act as a barrier to specific communities. We'll discuss how performing arts organizations are creating more inclusive practices to engage a more diverse range of performing artists, and we’ll consider questions of authentic experience and the actor’s craft.

Why is a more inclusive theater a...   More >
