Special Year Seminar II

Foundations of Matroids
10:00am|Simonyi 101 and Remote Access

The second lecture features the nuts and bolts of the invariants from first lecture, which we call foundations. We explain the structure theorem for foundations of ternary matroids, which is rooted in Tutte's homotopy theorem. We show how this...

Special Year Seminar II

Tits's Dream: Buildings Over F1 and Combinatorial Flag Varieties
11:00am|Simonyi 101 and Remote Access

The theme of the third lecture is the notion of points over F1, the field with one element. Several heuristic computations led to certain expectations on the set of F1-points: for example the Euler characteristic of a smooth projective complex...

Local-Global Principles and Effective Rates of Equidistribution For Semisimple Orbits
Andreas Wieser
3:30pm|Simonyi 101 and Remote Access

We prove an effective equidistribution theorem for semisimple
closed orbits on compact adelic quotients. The obtained error depends
polynomially on the minimal complexity of intermediate orbits and the
complexity of the ambient space. As an application...

  • Sebastian Haney (Columbia University) :Open enumerative mirror symmetry for lines in the mirror quintic

    One of the earliest achievements of mirror symmetry was the prediction of genus zero Gromov-Witten invariants for the quintic threefold in terms...

Computer Science/Discrete Mathematics Seminar I

Induced Subgraphs and Pathwidth
Maria Chudnovsky
10:30am|Simonyi 101 and Remote Access

Tree decompositions, and in particular path decompositions, are a powerful tool in both structural graph theory and graph algorithms. Many hard problems become tractable if the input graph is known to have a tree decomposition of bounded “width”...
