A conference in honor of Samson Shatashvili’s 60th birthday

The interactions of Mathematics and Physics have greatly intensified during the last three decades, and it led to a number of very significant breakthroughs in Mathematics. Among other things, these breakthroughs include new invariants of 3 and 4-dimensional manifolds, the discovery of mirror symmetry in Algebraic Geometry, and the theory of deformation quantization. This progress became possible due to close interactions between Mathematics and theoretical Physics and due to the dialogue between mathematicians and physicists working on similar problems but using very different methods.

The conference will touch upon two important aspects of interaction between Mathematics and Quantum Field Theory: Quantum Integrability and Anomalies. It will honour Professor Samson Shatashvili on the occasion of his 60th birthday.

Professor Samson Shatashvili made deep contributions in the theory of anomalies and in quantum integrability. In particular, in collaboration with L. Faddeev he discovered the interpretation of gauge theory anomalies in terms of abelian extensions of gauge groups on manifolds of odd dimension. In the theory of quantum integrability, together with a number of collaborators he discovered a deep link between Bethe equations and supersymmetric quantum gauge theory. Professor Shatashvili (of the Trinity College, Dublin and the Simons Center for Geometry and Physics, Stony Brook) served as a Louis Michel Chair and then as an Israel Gelfand Chair at IHES for many years. He contributed in a significant way in the development of ideas and in the unique research atmosphere of IHES.

Combinatorics and Arithmetic for Physics: special days

The meeting’s focus is on questions of discrete mathematics and number theory with an emphasis on computability. Problems are drawn mainly from theoretical physics (renormalisation, combinatorial physics, geometry) or related to its models.

Computation, based on combinatorial structures (graphs,trees, words, automata, semirings, bases) or classic structures (operators, Hopf algebras, evolution equations, special functions, categories) are good candidates for computer-based implementation and experimentation.

Algebraic Structures in Perturbative Quantum Field Theory
A conference in honour of Dirk Kreimer’s 60th birthday

On the occasion of Dirk Kreimer’s birthday, there will be a special issue of SIGMA on « Algebraic Structures in Perturbative Quantum Field Theory ».

Perturbative quantum field theory is essential for precision calculations of observables measured in experiments like the LHC, and therefore it is crucial for our understanding of the physics of the universe. At the same time, it is an extremely rich source of connections to a wide range of active research areas in mathematics. For example, Feynman integrals give rise to interesting motives and periods in algebraic geometry, their renormalization rests on combinatorial Hopf algebras underlying Feynman graphs, and further relations to noncommutative geometry and the moduli space of tropical curves and outer space have also been discovered.

This growing program keeps expanding in both breadth and depth, and exciting young researchers are entering the field. Now is an opportune time to bring together scientists working on all related aspects, to review old and new connections and to advance the state of the art. Lectures by established scientists will be accompanied by talks from young researchers, including a session dedicated to present and discuss open problems.

Close collaborations between mathematicians and physicists have been absolutely key for this kind of research, and many were initiated by Dirk Kreimer. Throughout his career, he made substantial contributions across these topics and led students and collaborators to the profound mathematical structures in perturbative quantum field theory that we are aware of today. Dirk Kreimer spent a particularly productive time at the IHES, and it is an honour that this workshop takes place in its inspiring and interdisciplinary environment.

MASAKI KASHIWARA and ALGEBRAIC ANALYSIS

The story starts in the sixties, when Mikio Sato introduces hyperfunctions by algebraic methods with the dream to treat classical problems of analysis with the tools of algebraic geometry, homological algebra and sheaves, what he called "Algebraic Analysis".

Holder of the AXA-IHÉS Chair of Mathematics

Certainly, geometry in the 21st century with physical application, will involve the study of new kinds of objects with categorical structures playing a primordial role.
Maxim Kontsevich has been a force of nature in creating these new categorical structures in the last 20 years.
The goal of this conference is to celebrate his contributions to Mathematics and Physics.
This meeting­ will contribute to disseminate results on­ a variety of subjects and will ­serve a perfect opportunity for young scientists to get involved in top research. ­
