C-motivic modular forms

We construct a topological model for cellular, 2-complete, stable C-motivic homotopy theory that uses no algebro-geometric foundations. We compute the Steenrod algebra in this context, and we construct a ???motivic modular forms??? spectrum over C.

Automated summary

This study presents a topological model for cellular, 2-complete, stable C-motivic homotopy theory that does not rely on algebro-geometric foundations. The Steenrod algebra is computed in this context, and a "motivic modular forms" spectrum over C is constructed.
