Abstract:
A complete description of Buchstaber formal groups F(u,v)=u2A(v)−v2A(u)uB(v)−vB(u),F(u,v)=u2A(v)−v2A(u)uB(v)−vB(u), in which the series A(x) and B(x) satisfy the relation A(x)ℓ=B(x)m, is given. A new family of Buchstaber formal groups depending on two algebraically independent parameters is obtained.
