### Lanthanide-based Nanomaterials: An Expanding Toolbox for Bioimaging and Photonic Applications

Seminar | April 22 | 11 a.m.-12 p.m. | 177 Stanley Hall

Xiaogang Liu, University of Singapore

Lanthanide-doped nanoparticles exhibit unique luminescent properties, including a large Stokes shift, a sharp bandwidth of emission, high resistance to optical blinking, and photobleaching. Uniquely, they can also convert long-wavelength stimulation into short-wavelength emission. These attributes offer the opportunity to develop alternative luminescent labels to organic fluorophores and quantum... More >

### Pocket Doctors: Disease Diagnosis with Mobile Phones

Seminar | April 22 | 11:10 a.m.-12:30 p.m. | 489 Minor Hall

Neuroscience Institute, Helen Wills

Light microscopy remains a central tool for disease diagnosis. Direct imaging of diseased tissues as well as quantification of pathogens in blood, sputum, and stool can enable rapid screening and diagnosis of multiple diseases. However, microscopy traditionally requires advanced equipment and skilled users not available outside of well-equipped laboratories and hospitals. In recent years, mobile... More >

### Combinatorics Seminar: Real-rooted h*-polynomials

Seminar | April 22 | 12:10-1 p.m. | 939 Evans Hall

Katharina Jochemko, KTH and Simons Institute

The Ehrhart polynomial counts the number of lattice points in integer dilates of a lattice polytope. The h*-polynomial encodes the Ehrhart polynomial in a particular basis. In this talk we give an introduction to the method of interlacing polynomials which is a powerful tool to prove that a polynomial has only real roots and present applications to h*-polynomials of zonotopes and dilated lattice...

### Probabilistic Operator Algebra Seminar: Matrix-valued measures in perturbation theory

Seminar | April 22 | 2-4 p.m. | 736 Evans Hall

Constanze Liaw, University of Delaware and CASPER at Baylor University

The Aronszajn-Donoghue theorem provides a good understanding of the subtle theory of rank one perturbations. One of their statements consists of the mutual singularity of the singular parts of the spectral measures under rank one perturbations. For higher rank perturbations, simple examples show that the singular parts can behave more complicatedly. Nonetheless, a 'vector' version of the mutual... More >

### String-Math Seminar: Mathematical hints of 3-d mirror symmetry

Seminar | April 22 | 2-3 p.m. | 402 LeConte Hall

Ben Webster, Perimeter Institute and University of Waterloo

3 dimensional \(N=4\) supersymmetric quantum field theories have two distinguished topological twists, called Higgs and Coulomb (though we periodically get confused about which is which). These two twists manifest very interesting mathematical objects in Lie theory and algebraic geometry, which don't seem to obviously be related, except through this bridge in QFT. I'll do my best to explain what... More >

### Arithmetic Geometry and Number Theory RTG Seminar: F-isocrystals with logarithmic decay, slope filtrations, and monodromy

Seminar | April 22 | 3-5 p.m. | 748 Evans Hall

Joe Kramer Miller, UC Irvine

Wan conjectured that the variation of zeta functions along towers of curves associated to the $p$-adic etale cohomology of a fibration of smooth proper ordinary varieties should satisfy several stabilizing properties. The most basic of these conjectures state that the genera of the curves in these towers grow in a regular way. We state and prove a generalization of this conjecture, which applies... More >

### Differential Geometry Seminar: Classification of Nahm Pole Solutions to the KW Equations on $S^1\times \Sigma \times \mathbb R^+$

Seminar | April 22 | 3:10-4 p.m. | 939 Evans Hall

Siqi He, Simons Center for Geometry and Physics (Stony Brook)

We will discuss Witten’s gauge theory approach to Jones polynomial by counting solutions to the Kapustin-Witten(KW) equations with singular boundary conditions over 4-manifolds. We will give a classification of solutions to the KW equations on $S^1\times\Sigma\times \mathbb R^+$ with $\Sigma$ a Riemann surface. We prove that all solutions to the KW equations over $S^1\times\Sigma\times... More >

### Documenting contact and change in Siberian multilingual contexts

Colloquium | April 22 | 3:10-5 p.m. | 370 Dwinelle Hall

Lenore Grenoble, University of Chicago

Multiple indigenous languages in Eurasia are undergoing change and loss as speakers shift to Russian. The language ecologies of the Sakha Republic (Yakutia) provide an excellent testing ground for hypotheses about the causes and effects of contact-induced language change. The Sakha language (Turkic) is spoken by a (slim) majority of residents of the Republic, with an estimated 500,000 speakers;... More >

### Aren’t “Gifted” and “Talented” the Same Thing?: Moving from Gifted Education to Talent Development

Colloquium | April 22 | 4-5:30 p.m. | Berkeley Way West, Room 1215 (2121 Berkeley Way, Berkeley, CA 94720)

Frank C. Worrell, Graduate School of Education, University of California, Berkeley

The concept of a free appropriate public education (FAPE) is typically applied to students with disabilities, but every student is entitled to a FAPE, including those at the upper end of the achievement distribution. Viewing giftedness as the outcome of a talent development process rather than the manifestation of a trait, I review the major conceptualizations in gifted education.

### Analysis and PDE Seminar: The nonlinear stability of the Schwarzschild family of black holes

Seminar | April 22 | 4:10-5 p.m. | 740 Evans Hall

Martin Taylor, Princeton University

I will present a theorem on the full finite codimension asymptotic stability of the Schwarzschild family of black holes. The proof employs a double null gauge, is expressed entirely in physical space, and utilises the analysis of Dafermos–Holzegel–Rodnianski on the linear stability of the Schwarzschild family. This is joint work with M. Dafermos, G. Holzegel and I. Rodnianski.
