DESCRIPTION:\n\n----------------------------------------- IMPORTANT INFORM
ATION ------------------------------------------ \n\nDue to the health sit
uation related to the Coronavirus epidemic\, the conference has been postp
oned from 16 to 20 November 2020.\n\n \n\nAlgebraic Structures in Perturb
ative Quantum Field Theory\n\nA conference in honor of Dirk Kreimer's 60th
birthday\n\nPerturbative quantum field theory is essential for precision
calculations of observables measured in experiments like the LHC\, and the
refore 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 wid
e range of active research areas in mathematics. For example\, Feynman int
egrals give rise to interesting motives and periods in algebraic geometry\
, their renormalization rests on combinatorial Hopf algebras underlying Fe
ynman graphs\, and further relations to noncommutative geometry and the mo
duli space of tropical curves and outer space have also been discovered.\n
\nThis growing program keeps expanding in both breadth and depth\, and exc
iting young researchers are entering the field. Now is an opportune time t
o bring together scientists working on all related aspects\, to review old
and new connections and to advance the state of the art. Lectures by esta
blished scientists will be accompanied by talks from young researchers\, i
ncluding a session dedicated to present and discuss open problems.\n\nClos
e collaborations between mathematicians and physicists have been absolutel
y key for this kind of research\, and many were initiated by Dirk Kreimer.
Throughout his career\, he made substantial contributions across these to
pics\, and led students and collaborators to the profound mathematical str
uctures in perturbative quantum field theory that we are aware of today. D
irk Kreimer spent a particularly productive time at the IHES\, and it is a
n honour that this workshop takes place in its inspiring and interdiscipli
nary environment.\n\n\nOrganisers: Erik PANZER (University of Oxford) & Ka
