DESCRIPTION:\n\nAlgebraic Structures in Perturbative Quantum Field Theory\
nA conference in honor of Dirk Kreimer's 60th birthday\n\nPerturbative qua
ntum field theory is essential for precision calculations of observables m
easured 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 ar
eas in mathematics. For example\, Feynman integrals give rise to interesti
ng motives and periods in algebraic geometry\, their renormalization rests
on combinatorial Hopf algebras underlying Feynman graphs\, and further re
lations to noncommutative geometry and the moduli space of tropical curves
and outer space have also been discovered.\n\nThis growing program keeps
expanding in both breadth and depth\, and exciting young researchers are e
ntering the field. Now is an opportune time to bring together scientists w
orking on all related aspects\, to review old and new connections and to a
dvance the state of the art. Lectures by established scientists will be ac
companied by talks from young researchers\, including a session dedicated
to present and discuss open problems.\n\nClose collaborations between math
ematicians and physicists have been absolutely key for this kind of resear
ch\, and many were initiated by Dirk Kreimer. Throughout his career\, he m
ade substantial contributions across these topics\, and led students and c
ollaborators to the profound mathematical structures in perturbative quant
um field theory that we are aware of today. Dirk Kreimer spent a particula
rly productive time at the IHES\, and it is an honour that this workshop t
akes place in its inspiring and interdisciplinary environment.\n\n\nOrgani
