Math alumnus Adam Marcus (2008 PhD in Algorithms, Combinatorics and Optimization) will be invited to speak at the next International Congress of Mathematicians, to be held in Seoul, Korea, August 13-21, 2014.

The International Congress of Mathematicians takes place every four years with over 4,000 mathematicians from all continents in attendance. The program consists of about 20 plenary one-hour lectures, about 160 invited 45-minute lectures held in 19 sections, and prize ceremonies, including the award of the Fields medals. Being invited to speak is a significant honor which indicates that the speaker's recent work is held in very high regard by the mathematical community.

Adam's talk is classified jointly in Section 8: Analysis and its Applications and Section 13: Combinatorics, and is a collaboration with his coauthors Daniel A. Spielman and Nikhil Srivastava.

It is notable that this will be the fourth International Congress, and the third in a row, with at least one of the invited speakers affiliated with the Algorithms, Combinatorics and Optimization Program.

Marcus, Spielman, and Srivastava recently solved the Kadison-Singer Problem, which has been open since 1959. A short, (three-page) purely expository paper that states Kadison-Singer (but is really about "frames", not K-S) can be downloaded from a recent AMS Notices.

Professor Ronghua Pan is the first mathematican to receive the Sciences without Borders, Special Visiting Researcher from the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) or the "National Counsel of Technological and Scientific Development" in Brazil.

This is a 3-year program intended to attract senior foreign researchers recognized internationally for leadership in the program's priority areas. This fellowship includes support for living expenses, when the researcher is in Brazil, as well funding for the local laboratory.

Ronghua will spend 3 months in 2013 in Brazil with his collaborator, Hermano Frid, at the Instituto Nacional de Matemática Pura e Aplicada (IMPA). In the second and third years of the fellowship, Ronghua plans to visit IMPA for one month each year. The fellowship also sponsors exchange students and post docs.

Alexander Schrijver from the University of Amsterdam and CWI Amsterdam will present the ACO Distinghished Lecture on January 28, 2014 at 4:30 pm with location to be announced.

Alexander Schrijver is a professor of mathematics at the University of Amsterdam and researcher at the Center for Mathematics and Computer Science (CWI) in Amsterdam. His research focuses on discrete mathematics and optimization, in particular on applying methods from fundamental mathematics. He is the author of four books, including 'Theory of Linear and Integer Programming' and 'Combinatorial Optimization - Polyhedra and Efficiency'.

He received Fulkerson Prizes in 1982 and 2003, Lanchester Prizes in 1987 and 2004, a Dantzig Prize in 2003, a Spinoza Prize in 2005, a Von Neumann Theory Prize in 2006, and an Edelman Award in 2008. He is a member of the Royal Netherlands Academy of Arts and Sciences since 1995 and of three foreign academies, received honorary doctorates from the Universities of Waterloo and Budapest, and was knighted by the Dutch Queen in 2005.


Graphs, Knots, and Algebras

Many graph invariants can be described as 'partition functions' (in the sense of de la Harpe and Jones). In the talk we give an introduction to this and we present characterizations of such partition functions among all graph invariants. We show how similar methods describe knot invariants and give rise to varieties parametrizing all partition functions. We relate this to the Vassiliev knot invariants, and show that its Lie algebra weight systems are precisely those weight systems that are 'reflection positive.'

The talk will be introductory and does not assume any specific knowledge on graphs, knots, or algebras.

There will be a reception in the Atrium of the building to be announced.

On Friday, January 31, 2014, Professor Mairi Sakellariadou from King's College London will make a presentation titled Particle Physics and Cosmology from Almost Commutative Manifolds.

The unification of the four fundamental forces remains one of the most important issues in theoretical particle physics.

In this talk, she will give a short introduction to Non-Commutative Spectral Geometry, a bottom-up approach that unifies the (successful) Standard Model of high energy physics with Einstein's General theory of Relativity. The model is built upon almost-commutative spaces and she will discuss the physical implications of the choice of such manifolds. She will show that even though the unification has been obtained only at the classical level, the doubling of the algebra may incorporate the seeds of quantization. She will then briefly review the particle physics phenomenology and highlight open issues and current proposals.

In the last part of her talk, she will explore consequences of the Gravitational-Higgs part of the spectral action formulated within such almost-commutative manifolds. In particular, she will study modifications of the Friedmann equation, propagation of gravitational waves and the onset of inflation. She will show how current measurements (Gravity Probe, pulsars, and torsion balance) can constrain free parameters of the model. She will conclude with a short discussion on open questions.

The event will be held at 4:00pm in Skiles, room 006
