aic Structures in Perturbative Quantum Field Theory\nA conference in honou
r of Dirk Kreimer's 60th birthday\n\nOn the occasion of Dirk Kreimer's bir
thday\, there will be a special issue of SIGMA on "Algebraic Structures in
Perturbative Quantum Field Theory".\n\nPerturbative quantum field theory
is essential for precision calculations of observables measured in experim
ents like the LHC\, and therefore it is crucial for our understanding of t
he physics of the universe. At the same time\, it is an extremely rich sou
rce of connections to a wide range of active research areas in mathematics
. For example\, Feynman integrals give rise to interesting motives and per
iods in algebraic geometry\, their renormalization rests on combinatorial
Hopf algebras underlying Feynman graphs\, and further relations to noncomm
utative geometry and the moduli space of tropical curves and outer space h
ave also been discovered.\n\nThis 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 rela
ted aspects\, to review old and new connections and to advance the state o
f the art. Lectures by established scientists will be accompanied by talks
from young researchers\, including a session dedicated to present and dis
cuss open problems.\n\nClose collaborations between mathematicians and phy
sicists have been absolutely key for this kind of research\, and many were
initiated by Dirk Kreimer. Throughout his career\, he made substantial co
ntributions 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 in
spiring and interdisciplinary environment.\n\n\nOrganisers: Erik PANZER (U
