### Computer Science/Discrete Mathematics Seminar II

Factors of sparse polynomials: structural results and some algorithms
Shubhangi Saraf
10:30am | Simonyi Hall 101
Are factors of sparse polynomials sparse? This is a really basic question and we are still quite far from understanding it in general. In this talk, I will discuss a recent...

### Emerging Topics working group

Coherence, planar boundaries, and the geometry of subgroups
Genevieve Walsh
11:00am | West Building Lecture Hall
Abstract: This will be a broad talk about coherence of groups, and how it relates to conjectures about hyperbolic groups with planar boundaries. A group is coherent if every...

### Institute for Advanced Study/Princeton University Joint Astrophysics Colloquium

Constraining Cosmic Reionization with Hubble, James Webb, and WFIRST
Brant Robertson
11:00am | Princeton University, Peyton Hall, Auditorium, Room 145
Understanding cosmic reionization requires the identification and characterization of early sources of hydrogen-ionizing photons. Through a series of intense observational...

### Variational Methods in Geometry Seminar

$alpha-harmonic$ maps between spheres
Tobias Lamm
1:00pm | Simonyi Hall 101
In a famous paper, Sacks and Uhlenbeck introduced a perturbation of the Dirichlet energy, the so-called $\alpha$-energy $E_\alpha$, $\alpha > 1$, to construct non-trivial...

### Variational Methods in Geometry Seminar

A mountain pass theorem for minimal hypersurfaces with fixed boundary
Rafael Montezuma
3:30pm | Simonyi Hall 101
In this talk, we will be concerned with the existence of a third embedded minimal hypersurface spanning a closed submanifold B contained in the boundary of a compact...

### Emerging Topics working group

One-relator groups, non-positive immersions and coherence
Henry Wilton
4:00pm | West Building Lecture Hall
Abstract: There seems to be an analogy between the classes of fundamental groups of compact 3-manifolds and of one-relator groups.  (Indeed, many 3-manifold groups are also...
