Variational Methods in Geometry Seminar

Extremal eigenvalue problems and free boundary minimal surfaces in the ball
10:00am|Simonyi Hall 101

When we choose a metric on a manifold we determine the spectrum of the Laplace operator. Thus an eigenvalue may be considered as a functional on the space of metrics. For example the first eigenvalue would be the fundamental vibrational frequency...

Computer Science/Discrete Mathematics Seminar I

Four and a half proofs of a product-measure version of the Erdös-Ko-Rado Theorem.
2:00pm|Simonyi Hall 101

The EKR theorem, which is the cornerstone of extremal combinatorics, characterizes maximal intersecting families of sets. Its setting fixes a ground set of size n, and then studies the size and structure of intersecting families of subsets of fixed...

Joint IAS/Princeton University Number Theory Seminar

Eisenstein ideal with squarefree level
4:30pm|Fine Hall 214

In his influential paper "Modular curves and the Eisenstein ideal", Mazur studied congruences modulo p between cusp forms and the Eisenstein series of weight 2 and prime level N. In particular, he defined the Eisenstein ideal in the relevant Hecke...
