报告摘要：
IBP reduction might be a major bottleneck in Feynman integral computations due to its high time and memory demands. In this talk, I introduce NeatIBP 1.1, a package that efficiently generates compact IBP systems. It uses modern computational algebra techniques to greatly reduce the size of IBP systems. Compared to the traditional Laporta algorithm, it is much faster and more efficient. The new version adds a Kira interface for automated IBP reduction. It also employs the spanning cuts method and an optimized syzygy algorithm to boost performance in complicated cases. Therefore, NeatIBP 1.1 is expected to become a powerful tool for handling ever more complicated integral computations.
个人简介：
Dr. Yingxuan Xu is currently a postdoctoral researcher at Humboldt University of Berlin and will soon be joining the Karlsruhe Institute of Technology (KIT). He earned his bachelor’s degree from Nankai University, his master’s degree from ETH Zurich, and his PhD from Humboldt University of Berlin. Dr. Xu’s research primarily focuses on scattering amplitude computations in high-energy physics and gravitational wave physics. His work encompasses integrals and precision calculations in QCD and gravitational wave processes, and the development of novel computational methods. To date, Dr. Xu has published five papers in international journals such as the Journal of High Energy Physics and Physical Review Letters, which have been cited 176 times.
