Regensburg scientists win prestigious prize in Beijing!
Prof. Dr. Guido Kings from the University of Regensburg and his former student Prof. Dr. Johannes Sprang from the University of Duisburg-Essen was awarded the 2025 Frontiers of Science Award of the International Congress of Basic Sciences. This prestigious honor has been awarded annually since 2023 for outstanding scientific publications and is endowed with $25,000. The award ceremony will take place on July 13, 2025 in Beijing, where Prof. Sprang will accept the award and give a presentation on their joint paper. Loud University of Regensburg The award-winning article is entitled: “Eisenstein-Kronecker classes, integrality of critical values of Hecke ???? -functions and ???? -adic interpolation” and appears in the Annals of Mathematics.
Kings and Sprang's work proves groundbreaking because it proves a nearly 50-year-old conjecture about the L-functions of Abelian varieties with complex multiplication. This conjecture was formulated in 1977 by N. Katz and P. Deligne. L-functions are invariants of systems of equations and provide fundamental information about them. The conjecture itself states that L-functions should take integer values, which results in surprising relations (congruences) between these functions. Kings and Sprang solve all remaining cases of the conjecture and introduce a new construction, the Kronecker-Eisenstein classes.
Background of the award
The International Congress of Basic Sciences, which awards the prize, honors outstanding research achievements from the last five years. This award covers both fundamental and applied research in 34 areas of fundamental science, spanning math, theoretical physics, and theoretical computer and information science. To be considered, a publication must have appeared within the last five years and be of high scientific value and originality University of Toronto reported.
The aim of the award is to encourage young scientists to conduct research at the frontiers of basic science and achieve significant results. In the mathematics category, the 2023 prize winners also included well-known scientists such as Alexander Braverman and Jacob Tsimerman.
Prof. Guido Kings and Prof. Johannes Sprang
Prof. Dr. Guido Kings, who studied mathematics and philosophy at the Universities of Bonn and Princeton, received his doctorate from the University of Münster in 1994 and completed his habilitation in 2000. In 2001, he took on a research professorship at the Max Planck Institute for Mathematics in Bonn and the Chair of Mathematics at the University of Regensburg. Since 2014 he has been the spokesman for the Collaborative Research Center 1085 “Higher Invariants” in Regensburg. Kings has received several awards and, among other things, has been a Fellow of the American Mathematical Society since 2012.
His former student Prof. Dr. Johannes Sprang also received his doctorate and habilitation in Regensburg and has been a professor (tenure track) in Duisburg-Essen since 2021. He is also Principal Investigator in the SFB 1085 “Higher Invariants”.
This award highlights the importance of their research and the need to continue working on the fundamental questions of mathematics in order to gain new insights. The outstanding scientific value of Kings and Sprang's work is evidenced by its widespread acceptance in the professional community, resulting in a significant impact on their field, as well Donors' Association highlights.
