Realization of Abel's universal formal group law

To a complex oriented cohomology theory one may assign a formal group law over . The purpose of this paper is to show that the converse holds true for the case of Abel's universal formal group law , i.e. we will prove the existence of a complex oriented cohomology theory whose formal group law is isomorphic to .
