| PI Contribution | This colloboration is on 'Modular graph forms from equivariant iterated Eisenstein integrals': Joshua Drewitt worked with Nils Matthes to help provide a Number theory perspective to the problem in String theory of understanding modular graph forms, and how they connect to Francis Brown's real analytic modular forms. He used his previous reserach on real analytic modular forms including his work on 'Laplace-eigenvalue equations for length three modular iterated integrals' to help find this connection. |
| Collaborator Contribution | Using the above Daniele Dorigoni, Axel Kleinschmidt and Oliver Schlotterer built upon their previous theory from 'Poincaré series for modular graph forms at depth two' Parts I and II to provide the first validations that modular graph forms are contained in the space of real analytic modular forms. Mehregan Doroudiani, Martijn Hidding, and Bram Verbeek were also crucial in providing this validation and were a key part of producing a large dataset of explicit examples in mathematica. |
