Abstract This concern about an abstract for an application for a FAPESP postdoc position at Instituto de Ciências Matemáticas e Computação - ICMC in São Carlos under supervision of professor Herivelto Martins Borges Filho from May 2018 till April 2020. \\My research plan concerns, among other things, questions that follow from my doctoral thesis and research in rational points theory and Hall algebras. We outline these topics in brevity. More details can be found in the research plan.Motivated by Zagier's work, Lorscheid develops in his doctoral thesis the theory of "graphs of Hecke operators", which plays an important role in the proofs of his main theorems. In my Ph.D thesis, we extend this theory from $\mathrm{PGL}_2$ to $\mathrm{GL}_n$, generalize some results of Lorscheid and describe these graphs for the projective line and elliptic curves. In the case of elliptic curves, we use the connection with the Hall algebra of the category of coherent sheaves.Our first project concerns an application of our results to explicit calculations with automorphic forms. Our second project is to describe these graphs for the weighted projective line and curves of large genus. A third project is dedicated to investigate the Hall algebra of an elliptic curve in more detail. Besides proceeding with follow-up projects from my doctoral research, I am interested in extending my research horizon towards problems in rational points, like height functions, ranks and the torsion points of elliptic curves, Zariski density, Manin's conjecture, and related topics. I am also interested in bounds for the number of rational points of curves over finite fields, justifying the importance of professor Herivelto Borges, and their applications to coding theory. | |
