Geometry, Topology and Physics SwissMAP project organizes a yearlong master class at University of Geneva in the academic year 2016/2017 for master and beginning PhD students. The program includes courses in symplectic and Poisson geometry, algebraic geometry, moduli spaces, quantum topology, and field theory.
Deadline for registration is December 31, 2015 (closed).
Description
Geometry and physics have been interconnected since ancient times, providing inspiration and intuition, as well language for each other. Geometric ideas lay in the foundations of electromagnetism, special and general relativity, while symplectic geometry is the modern language of mechanics, which, in turn, provides it with methods and motivation.
The 20162017 master class covers some of the most important and actively developed subjects of the research area inbetween geometry, topology and physics providing an entry point into the forefront research for students starting to work in this field.
The program is aimed at Master students and beginning PhD students. The participants will enroll in a oneyear program at the University of Geneva starting in September 2016, providing 60 ECTS credits. Participants will be offered the possibility of obtaining a master degree from the university of Geneva by completing a Master thesis for 30 additional ECTS credits.
Tuition fee for regular (master) students at the University of Geneva is 500 Swiss Francs per semester. There is no tuition fee for exchange students.
A number of fellowships covering accommodation and local expenses are available.

Symplectic geometry of moment maps (A. Alekseev)
Equivariant symplectic geometry or moment map theory is the field built around several extraordinary results: the MarsdenWeinstein symplectic reduction theory, moment map convexity theorems, DuistermaatHeckman localization for oscillating integrals, and the "quantization commutes with reduction" principle. The goal of the course is to give an introduction into the field and to discuss (some of) these important results.
Program of the course:
 Basics of symplectic geometry: definition, examples
 Recall: group actions of compact groups, normal forms on a neighborhood of an orbit
 Recall: Morse theory, Morse inequalities, perfect Morse functions
 Hamiltonian Gspaces: definition, examples
 Symplectic reduction, examples. Symplectic cuts
 AtiyahGuilleminSternberg convexity theorem
 DuistermaatHeckman localization I: BerlineVergne approach
 Equivariant cohomology: Cartan model, examples
 Localization II: AtiyahBott approach
 Kirwan surjectivity theorem, intersection pairings on reduced spaces
 G nonabelian: what changes?
 Kähler manifolds, geometric quantization, GuilleminSternberg [Q,R]=0.
prerequisites: differential geometry

Poisson geometry and quantization (P. Ševera)
Poisson geometry, or the geometry of Poisson brackets, is a natural generalization of symplectic geometry. It originates from classical mechanics. A celebrate theorem of Kontsevich and Tamarkin states that any Poisson structure can be "quantized", i.e. turned to a noncommutative deformation of the algebra of functions on the manifold. The first aim of the course is to give an introduction to Poisson geometry and some of the most interesting examples of Poisson manifolds, in particular PoissonLie groups. We shall then study Drinfeld associators, which provide a link between braids and the problem of quantization of Poisson manifolds. While Drinfeld associators can be used to quantize all Poisson manifolds, we shall content ourselves with a simple method of quantization of the most interesting examples, in particular of PoissonLie groups.
Program of the course:
 Poisson structures and symplectic leaves
 Deformation quantization, Moyal product
 The Poisson structure on the dual of a Lie algebra, moment maps
 PoissonLie groups and Lie bialgebras
 Moduli spaces of flat connections and their Poisson structures
 KnizhnikZamolodchikov equation and Drinfeld associator
 Braided monoidal categories and construction of noncommutative algebras
 Quantization of Lie bialgebras
 Quantization of moduli spaces
 Drinfeld associators and the GrothendieckTeichmueller group
prerequisites: differential geometry, Lie theory

Topological aspects of algebraic geometry I (I. Itenberg)
Algebraic geometry is geometry of varieties defined by polynomial equations. Coefficients of these equations may be of different nature, classically the main examples are integer, real and complex coefficients. The fields of real and complex numbers come with a natural Euclidean topology. This makes real and complex algebraic varieties especially nice and accessible to techniques going beyond standard commutative algebra considerations.
We start the course by topological theory of algebraic curves in the real plane (this subject goes back to Harnack, Klein, and Hilbert and is sometimes referred as Hilbert's 16th problem). Then we look at the socalled amoebas of complex algebraic varieties as well as a certain limiting procedure known as the tropical limit. The limiting objects are themselves subject to a kind of algebraic geometry known as tropical geometry.
prerequisites: basic geometry and topology courses

Topological aspects of algebraic geometry II (G. Mikhalkin)
see description in first semester

Symmetries and moduli spaces I (S.Galkin)
The purpose of the course is to give an introduction to the construction and geometric properties of moduli spaces from the point of view of algebraic geometry. These spaces appear in physics as well, as ground states of various gauge theories. A central tool in the construction of moduli spaces is an appropriate notion of symmetries, represented by groups acting on spaces, and the introduction of these objects into algebraic geometry will be the central theme of the course.
Program of the course:
 Projective and affine algebraic varieties, smooth points and singularities.
 Algebraic groups and representations. Vector bundles.
 First examples: projective spaces and grassmannians.
 Toric varieties: Polytopes and fans.
 Toric varieties: Chambers and quotient constructions.
 Intersection theory and vector bundles.

Symmetries and moduli spaces II (A. Szenes)
continuation:
 More quotients: grassmannians and flag varieties.
 Configuration of points on the line: the HilbertMumford criterion.
 Vector bundles on Riemann surfaces: classification.
 Quot schemes and the construction of the moduli spaces of vector bundles.
 Intersection theory on quotients.

Introduction to quantum topology I (A. Virelizier)
Quantum Topology (QT) is a branch of mathematics that studies various applications of methods and principles of quantum theory in lowdimensional topology. Historically, QT came to existence in 80’s with the discovery by V. Jones of his famous polynomial invariant of knots. Among the important mathematical notions related to QT is that of a Topological Quantum Field Theory (TQFT), i.e., a quantum field theory that has topological invariants as its observables. Important examples of TQFTs are related with quantum ChernSimons gauge field theory in 2+1 dimensions and the theory of quantum groups. The problem of understanding quantum ChernSimons theory with noncompact gauge groups is of special importance and interest because of its connections to geometric approach of Thurston to topology of 3manifolds, as well as 2+1dimensional quantum gravity.
The course will start with basics on knot diagrams and Reidemeister moves, the Jones Polynomial, quantum groups and their finite dimensional representations, Rmatrices, monoidal (fusion, modular,…) categories, Kirby calculus, and then continue with more advanced constructions of TQFTs, in particular, constructions related to ChernSimons theories with noncompact gauge groups in the case of Teichmüller spaces of punctured surfaces.
prerequisites: basic courses in algebra, geometry, topology, and analysis.
