KaMCAM · Kac-Moody groups and Computer Assistants in Mathematics

This fellowship will enable the experienced Researcher Dr Rieuwert Blok - a currently USA-based European Union national - and Dr Corneliu Hoffman - as Host researcher based at the University of Birmingham - to carry out innovative and mutually beneficial research utilising their complementary skill sets. Blok brings extensive research experience in buildings, Lie theory and geometries while Hoffman's background is in group theory, representation theory and number theory. The fellowship aims to create optimal conditions for the Researcher to reintegrate into ERA for the benefit of both the Researcher and the ERA.The action comprises two distinct, yet interconnected Work Packages . The first one concerns Curtis-Tits groups, a large family of groups recently introduced by the Researcher and Dr Hoffman.This family includes groups of established importance, namely groups of Lie and Kac-Moody type, but in fact contains many new groups of great theoretical significance and practical interest.The action develops methods that open up this promising family for further study. It then determines key properties such as simplicity, and explores and establishes applications in geometric group theory, combinatorics, group presentations, and computer science. The subject area is an innovative blend of group theory, homological algebra, topology, geometry, number theory and computer science. The second package is an interdisciplinary project between mathematics and computer science, exploring the promise of effectively using the recent developments surrounding proof assistants in teaching and research. It builds forth upon pioneering work in this direction by both researchers at their respective universities.
