Vivek Labhishetty's Abstract
Retinal-Conjugate Surfaces: The Blur Horopter
When we fixate at an object, the image of that object is brought to sharp focus on the fovea due to the eyes accommodation. Other objects in the periphery may be farther or nearer than best focus on those parts of the retina. We measured the shape of surface of best focus in the world as the eye accommodates to... More >

The classical volume polynomial in algebraic geometry measures the degrees of ample (and nef) divisors on a smooth projective variety. We introduce an analogous volume polynomial for matroids, give a complete combinatorial formula, and show that it is a valuation under matroid polytope subdivisions. For a realizable matroid, we thus obtain an explicit formula for the classical volume polynomial... More >

In many situations, two or more sources have some information about a target. For instance, sensory input and context information can jointly determine the firing pattern of a neuron. Since the information from the two sources is typically not identical, one wishes to decompose it in those parts that are unique to each source, what is shared between them and what is complementary, that is,...

Where better to bring our grief than the garden? In this contemplative photography workshop, we will observe Natures teachings on letting go, and we will use the camera as a trusted guide who can navigate us safely through the rugged terrain of grief.

Gukov, Putrov and Vafa postulated the existence of some 3-manifold invariants, obtained by counting BPS states in the \(3d\), \(N=2\) theory \(T[M_3]\). The GPV invariants take the form of power series converging in the unit disk, and whose radial limits at the roots of unity give the Witten-Reshetikhin-Turaev invariants. Furthermore, these power series have integer coefficients, and should admit... More >
Jesse Zymet, "Lexical propensities in phonology: Corpus and experimental evidence, grammar, and learning"
Colloquium | September 17 | 3:10-5 p.m. | 370 Dwinelle Hall
Jesse Zymet, UC Berkeley
Traditional theories of phonological variation propose that morphemes be encoded with descriptors such as [+/- Rule X], to capture which of them participate in a variable process. More recent theories predict that individual morphemes can have lexical propensities: idiosyncratic, gradient rates at which they participate in a processe.g., [0.7 Rule X]. In this talk, I argue that such propensities... More >

Suppose $(X, \omega )$ is a Kähler manifold induced by an ample line bundle $(L, X)$. We introduce $L^p$-type Finsler structures on the space of holomorphic sections of $L^k$, and show that the resulting metric spaces quantize the $L^p$-Mabuchi metric structures on the space of Kähler metrics, up to their completion. This is joint work with C.H. Lu and Y.A. Rubinstein.

We will describe how the crystalline cohomology of a supersingular K3 surface gives rise to certain one-parameter families of K3 surfaces, which we call supersingular twistor spaces. Our construction relies on the special behavior of $p$-torsion classes in the Brauer group of a supersingular K3 surface, as well as techniques coming from the study of derived categories and Fourier–Mukai...

The AdS instability conjecture is a conjecture about the initial value problem for the Einstein vacuum equations with a negative cosmological constant. It states that there exist arbitrarily small perturbations to the initial data of the AdS spacetime which, under evolution by the vacuum Einstein equations with reflecting boundary conditions on conformal infinity, lead to the formation of black...
