Web1) Modular forms are shiny: they satisfy or explain many beautiful and surprising numerical identities (about partitions and sums of square among others). This got them noticed in the first place. 2) Modular forms have Galois representations, and conversely Galois representations often come from modular forms. Webin other cases.

WebThis tells us that we can see modular forms as holomorphic di erential forms f(z)(dz)k on the space H=SL(2;Z). For instance, modular forms of weight 2 will be di erential 1-forms f(z)dzon the fundamental domain with appropriate identi cations. This di erential form is allowed to have a simple pole at 1: Substituting q= e2ˇiz, we get f(z)dz= g ...
