### Between-individual variation in the human retina ultrastructure: the key for understanding everything from myopia to AMD?

Seminar | May 6 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

Rigmor Baraas, OD, PhD, National Centre for Optics, Vision and Eye Care, Department of Optometry, Radiography and Lighting Design, University of South-Eastern Norway, Kongsberg, Norway

Optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) have become invaluable tools for mapping the ultrastructure of the retina in living humans. OCT imaging has revealed considerable variation in retinal layer thickness, foveal shape and morphology. AOSLO imaging has revealed large variation in cone mosaics, both peak and eccentricity dependence density...   More >

### Combinatorics Seminar: LLT Polynomials, k-Schur Functions, and Positivity

Seminar | May 6 | 12:10-1 p.m. | 939 Evans Hall

Christopher Miller, UC Berkeley

Department of Mathematics

Both LLT polynomials and k-Schur functions were derived from the study of Macdonald polynomials, and have proved to be fruitful areas of study. A conjecture due to Haglund and Haiman states that k-bandwidth LLT polynomials expand positively into k-Schur functions. This is trivial in the case k=1 and has been recently proved for k=2. In this talk, I will present a proof for the case k=3. To this...   More >

### String-Math Seminar: Searching for Lie groups of the XXI century

Seminar | May 6 | 2-3 p.m. | 402 LeConte Hall

Andrei Okounkov, Columbia University

Department of Mathematics

It has been understood for some time now that many highlights of Lie theory, such as the representation-theoretic theory of special functions, or the Kazhdan–Lusztig theory, have a natural extension to a much broader setting, the boundaries of which are yet to be explored. In this extension, the focus is shifting from a group $$G$$ to various classes of algebraic varieties that possess the key...   More >

### Northern California Symplectic Geometry Seminar: Divisor complements in Calabi-Yau symplectic manifolds

Seminar | May 6 | 2:30-3:30 p.m. | 384H STANFORD

Umut Varolgunes, Stanford

Department of Mathematics

Let $(M,\omega )$ be a closed symplectic manifold. Consider a closed symplectic submanifold $D$ whose homology class is a positive multiple of the Poincare dual of $[\omega ]$. The complement of $D$ can be given the structure of a Liouville manifold, with skeleton $S$. We prove that $S$ cannot be displaced from itself inside $M$ by a Hamiltonian isotopy if we assume that $c_1(M)=0$. Under the...   More >

### Between Shannon and Hamming: how bad can the channel be?: BLISS Seminar

Seminar | May 6 | 3-4 p.m. | 540 Cory Hall

Anand Sarwate, Rutgers

The information theory community has traditionally studied two different models for communication. The Shannon-theoretic model treats the channel’s impact as random, so codes must correct almost all error patterns of a given weight; this is an average-case analysis. The coding-theoretic (Hamming-theoretic?) model treats the channel as adversarial, so codes must correct all error patterns of a...   More >

### Differential Geometry Seminar: Moduli spaces of spherical surfaces with conical singularities

Seminar | May 6 | 3:10-4 p.m. | 939 Evans Hall

Dmitri Panov, University College London

Department of Mathematics

A spherical surface with $n$ conical singularities is a surface $S$ with cone points $x_1, \dots ,x_n$ and a metric $g$, such that $g$ has curvature 1 on the complement $S \setminus (x_1,...,x_n)$ and has a conical singularity of angle $2\pi (\theta _i)$ at each $x_i$. Moduli spaces of spherical metrics with fixed angles are intriguing objects. Up to very recently the most basic questions about...   More >

### A French Revolution for the Third Millennium?: The Reimagining of Higher Education in Contemporary France

Colloquium | May 6 | 4-5:30 p.m. | 1215 Berkeley Way West

Grace Neville

Human Resources

In 2009 the President of France, Nicolas Sarkozy, invited two highly respected, leading French politicians, Michel Rocard and Alain Juppé, both former Prime Ministers, one centre-left and the other centre-right, to identify the national priorities to be followed over the ensuing years. The Rocard-Juppé report was accepted by the French parliament with immediate effect. Most of its initial budget...   More >

### Northern California Symplectic Geometry Seminar: Quantum topology from symplectic geometry

Seminar | May 6 | 4-5 p.m. | 383N STANFORD

Vivek Shende, UC Berkeley

Department of Mathematics

The discovery of the Jones polynomial in the early 80s was the beginning of "quantum topology": the introduction of various invariants which, in one sense or another, arise from quantum mechanics and quantum field theory. There are many mathematical constructions of these invariants, but they all share the defect of being first defined in terms of a knot diagram, and only subsequently shown by...   More >
