fourmodule
A fourmodule is a mathematical concept used in the study of modular forms and number theory. It is a specific type of modular form that has a certain symmetry property, known as a fourfold symmetry, which is reflected in its transformation behavior under the action of the modular group. The fourmodule is defined over the upper half-plane in the complex plane and is invariant under the action of the modular group, which consists of transformations that preserve the shape of the upper half-plane.
The fourmodule is a generalization of the classical modular form, which is invariant under the action of
The fourmodule is a powerful tool in the study of modular forms and has been used to
