FWF Stand-Alone-Project: Computer Algebra for Multi Loop Feynman Integrals

[planned start: September 2021]

SFB AEC: Algorithmic and Enumerative Combinatorics

I am co-speaker of the Special Research Program (SFB, in short for the German name SpezialForschungsBereich) Algorithmic and Enumerative Combinatorics which started in March 2013. It is a special effort of three institutes, the Faculty of Mathematics (University of Vienna), the Institute for Discrete Mathematics and Geometry (Technical University Vienna), and the Research Institute for Symbolic Computation (Johannes Kepler University Linz) funded by the Austrian Science Funds (FWF).
In my project part "Computer algebra of nested sums and products" the research topics mentioned above will be pushed forward in the context of combinatorial problems.

ITN SAGEX: Scattering Amplitudes: from Geometry to Experiment

In the Innovative Training Network (ITN) SAGEX, a Marie Skłodowska-Curie Innovative Training Network funded by the European Commission, an international team consisting of physicists and mathematicians aims at gaining deeper insight and knowledge within the field of particle physics. In particular, in the project
ESR 15: ``Computer algebra for special functions ''
carried out at RISC we will exploit the fact that many arising problems in the network SAGEX can be formulated in terms of complicated integrals/sums or as strongly-coupled systems of difference/differential equations. Given such an input, we aim at better representations of these sums and integrals and extracting the desired physical information. In order to accomplish this task, new symbolic summation/integration algorithms and special function algorithms will be developed.
