Abstract

I will give a brief introduction into how Elliptic curves can be used to define complex oriented
cohomology theories. I will start by introducing complex oriented cohomology theories, and then move onto
formal group laws and a theorem of Quillen. I will then end by showing how the formal group law associated
to an elliptic curve can, in many cases, allow one to define a complex oriented cohomology theory.
