modular form

In mathematics, a modular form is a (complex) analytic function on the upper half-plane, ${\\displaystyle \\,{\\mathcal {H}}\\,}$ , that satisfies :
- a kind of functional equation with respect to the group action of the modular group,
- and a growth condition.
The theory of modular forms therefore belongs to complex analysis. The main importance of the theory is its connections with number theory. Modular forms appear in other areas, such as algebraic topology, sphere packing, and string theory.
