### Geometric Representation Theory Seminar: Microlocal mirror symmetry and a new coherent theory on open manifolds

Seminar | November 29 | 11 a.m.-12:30 p.m. | 732 Evans Hall

Dmitry Vaintrob, IAS

I will talk about my recent proof of a mirror symmetry statement for microlocal Fukaya categories associated to an $n$-dimensional symplectic cylinder, $T^*(S^1)^n$. Along the way I will define a remarkable new category of coherent sheaves, which I call the log-coherent category (a close cousin of the parabolic coherent category), associated to an open algebraic variety $U$ with choice of...

### “Diagnosing Disease on a Microchip: Scaling Up Micro- and Nano-Scale Diagnostics”

Seminar | November 29 | 12-1 p.m. | 290 Hearst Memorial Mining Building

David Issadore, Assistant Professor of Bioengineering, University of Pennsylvania

The transformative growth in microelectronics in the latter half of the 20th century was fueled fundamentally by the ability to simultaneously miniaturize and integrate complex circuits onto monolithic chips. The impact of this growth has been profound– computing is pervasive and portable, communication is instant and global, and information is ubiquitously gathered and shared. My research aims... More >

### Decoding the computations of high-level auditory neurons

Seminar | November 29 | 12 p.m. | 560 Evans Hall

Joel Kaardal, Salk Institute

Neuroscience Institute, Helen Wills

Characterizing the computations performed by high-level sensory regions of the brain remains enigmatic due to the many nonlinear signal transformations that separate the input sensory stimuli from the neural responses. In order to produce interpretable models of these computations, dimensionality reduction techniques can be employed to obtain a description of the neural computation in terms of a... More >

### Topology Seminar (Introductory Talk): Computational complexity in geometric topology

Seminar | November 29 | 2-3 p.m. | 740 Evans Hall

Eric Samperton, University of California, Davis

I’ll give an overview of what is known about the computational complexity of problems in geometric topology. I will introduce the necessary complexity theory as we go, and focus especially on 3-dimensional problems.

### Regularity and strict positivity of densities for the nonlinear stochastic heat equation

Seminar | November 29 | 3:10-4 p.m. | 1011 Evans Hall

Le Chen, University of Nevada, Las Vegas

In this talk, I will present some recent progress in understanding the existence, regularity and strict positivity of the (joint-) density of the solution to a semilinear stochastic heat equation. The talk will consists two parts. In the first part, I will show that under a mild cone condition for the diffusion coefficient, one can establish the smooth joint density at multiple points. The tool... More >

Klara Nahrstedt, University of Illinois Urbana-Champaign

Electrical Engineering and Computer Sciences (EECS)

Multi-camera content delivery systems are becoming an integral part of our video consumption, enabling advanced teleimmersive interactions in arts and sciences, 360-degree video viewing of YouTube content, and enhanced broadcasting experience of live events. However, multi-camera content systems generate high volume, variety and velocity data that present multiple orders of magnitude higher... More >

### Representation Theory and Mathematical Physics Seminar: Integration of poly-Poisson structures

Seminar | November 29 | 4-5 p.m. | 939 Evans Hall

Ivan Contreras, University of Illinois, Urbana Champaign

Poly-Poisson geometry can be traced back to de-Donder and Weyl in 1930's. This approach leads to a poly-symplectic formulation of Lagrangian field theories, with several applications to mechanics. In this talk we address the problem of integration of poly-Poisson manifolds via Lagrangian field theories with boundary, which is a natural extension of the Poisson sigma model. Joint work with N.... More >

### Topology Seminar (Main Talk): Coloring invariants of knots are often intractable

Seminar | November 29 | 4-5 p.m. | 3 Evans Hall

Eric Samperton, University of California, Davis

Given a finite group $G$, we get an invariant of a knot $K$ by counting the number of $G$-colorings of $K$, i.e., the number of homomorphisms $\pi_1(S^3 \setminus K) \to G$. When $G$ is the dihedral group of order 6, this invariant is basically the number of Fox 3-colorings of $K$. We will show that when $G$ is non-abelian simple, the coloring invariant is #P-complete.

I discussed a similar... More >

### Causal Inference in the Presence of Interference

Seminar | November 29 | 4-5 p.m. | 1011 Evans Hall

Michael Hudgens, UNC-Chapel Hill

A fundamental assumption usually made in causal inference is that of no interference between individuals (or units), i.e., the potential outcomes of one individual are assumed to be unaffected by the treatment assignment of other individuals. However, in many settings, this assumption obviously does not hold. For example, in infectious diseases, whether one person becomes infected depends on who... More >

### New Insights into Hydrophobic Interactions Encoded by Chemical Nanopatterns

Colloquium | November 29 | 4-6 p.m. | 180 Tan Hall

Nicholas L. Abbott, University of Wisconsin-Madison

Department of Chemical Engineering

The structuring of water near non-polar molecular fragments or surfaces mediates cohesive interactions (so-called hydrophobic interactions) that underlie a broad range of biophysical, colloidal and materials-related phenomena. Substantial progress has been made during the past decade towards understanding hydrophobic interactions in simple model systems, but in most biological and technological... More >
