ECH is one of the 3 isomorphic Floer homologies which apply to 3-manifolds, (symplectic) 4-manifolds, and relations between them. It is defined by “counting” holomorphic curves and periodic orbits, and a big part of this course will be to study its foundations and difficulties (which plague other contact homologies. Some applications of ECH to be described include 1) distinguishing contact 3-manifolds and symplectic 4manifolds, 2) the Weinstein conjecture on the existence of periodic orbits, and 3) the relations to SeibergWitten theory.

Algebraic cobordism is a cohomology theory for schemes constructed by Vladimir Voevodsky in the context of stable motivic homotopy theory, and greatly expanded by Marc Levine and Fabien Morel. It is, in some sense, simultaneously a generalization of “Fulton-style” intersection theory for Chow groups and a simplification of the latter theory. The course will revolbe around a theorem of Levine and Morel which recovers the Chow groups from algebraic cobordism. To do this, we will explain the notion of an oriented theory in algebraic geometry and prove that algebraic cobordism is the “universal” oriented theory. From there, we will prove the basic theorems (such as localization, homotopy invariance, computation of the coefficient ring and the degree formula) and give a sampler of computations. Further topics will depend on the interests of the participants.

This course will provide an elementary introduction to the combinatorial aspects of Schubert calculus, the part of enumerative geometry dealing with classical varieties such as Grassmanians, flag varieties, and their Schubert varieties. A classical example of a Schubert calculus question is the following: given a generic configuration of four 2-dimensional subspaces in a complex 4-dimensional space, how many 2dimensional subspaces intersect each of these four in a line? To be able to answer this and related questions, one needs to concretely understand the structure of the cohomology ring of the Grassmanian. In this course we will develop the necessary combinatorial machinery to answer such enumerative questions, including Young tableaux, the Bruhat order, symmetric functions, and Schubert polynomials. More advancd topics may include (time-permitting): quantum cohomology rings, toric Schur functions, real Schubert calculus.

Quantum spin systems lie at the interface of theoretical physics and mathematical spectral theory. They allow us to study true many-body phenomena, like phase transitions, within a solid mathematical framework. In this topics class, we will study the basic notions, main results, and open problems, of quantum spin systems. Two highlights will be the derivation of a spectral gap in the AKLT chain and the proof of spontaneous breaking of SU(2) symmetry in the Heisenberg antiferromagnet by Dyson, Lieb, and Simon. We will mainly use methods from spectral theory and matrix analysis, as well as some representation theory of SU(2).

This is a topics course on non-Kahler complex geometry, with a focus on non-Kahler Calabi-Yau threefolds. These objects were proposed as heterotic string compactifications by C.Hull and A. Strominger. Some of the mathematical structures which emerge include Hermitian-Yang-Mills connections, special holonomy constraints, Michelsohn’s notion of balanced metrics, and Hitchin’s generalized complex geometry. We will also discuss analytic methods in this field, as developed by J. Li, J.-X. Fu, and S.T. Yau.

The main goal will be to study smooth 4-manifolds. The plan is to start with knots in 3-manifolds and their interactions with smooth 4-manifold theory. Topics will be chosen from the topoloogy of 4-manifolds via their handlebodies, such as various constructions of 3-and 4-manifolds, by using techniques from gluing, carving, roping, corks, plugs, Gluck construction, and applications of some 4-manifold invariants to these constructions, and state some open problems.
