Minerva Mini-Course

An overview of Benjamini-Schramm convergence in group theory and dynamics
Lewis Bowen
1:30pm|Fine 110, Princeton University

Finite models of infinite groups/actions/manifolds are useful for studying spectral and $L^2$-invariants, constructing random processes and have recently been used to introduce new invariants of group actions useful for proving nonembedding and...

Joint IAS/Princeton University Number Theory Seminar

Unlikely intersections for two-parameter families of polynomials
Tom Tucker
4:30pm|Fine 214, Princeton University

Inspired by work of Masser and Zannier for torsion specializations of points on the Legendre elliptic curve, Baker and DeMarco proved that if $v$, $w$ are two points in $C$, then there are at most finitely many $t$ in $C$ such that $v$ and $w$ are...

Geometric Structures on 3-manifolds

Non-orientable knot genus and the Jones polynomial
4:00pm|S-101

The non-orientable genus (a.k.a crosscap number) of a knot is the smallest genus over all non-orientable surfaces spanned by the knot. In this talk, I’ll describe joint work with Christine Lee, in which we obtain two-sided linear bound of the...

Geometric Structures on 3-manifolds

Geometric techniques in knot theory
Jessica S. Purcell
2:00pm|S-101

We will discuss methods of decomposing knot and link complements into polyhedra. Using hyperbolic geometry, angled structures, and normal surface theory, we analyze geometric and topological properties of knots and links.

Members’ Seminar

Subgroups of random groups
2:00pm|S-101

What can you learn about a group from a presentation? Sometimes very little; almost every interesting problem about groups given by (finite) presentations is unsolvable in full generality. But if one asks about *typical* groups - so-called "random"...

Mathematical Conversations

Finite simple groups
6:00pm|Dilworth Room

The classification of finite simple groups is a singular event in the history of mathematics. It has one of the longest and most complicated proofs any theorem (indeed just to define the terms in the statement of theorem requires a lot). It has many...

Joint IAS/Princeton University Symplectic Geometry Seminar

3d mirror symmetry and symplectic duality
Tudor Dimofte
3:00pm|Fine 224, Princeton University

In recent work of Braden, Licata, Proudfoot, and Webster, a "symplectic duality" was described between pairs of module categories $O(M)$, $O(M')$ associated to certain pairs of complex symplectic manifolds $(M, M')$. The duality generalizes the...
