 I would present some recent results related to the computations of the Euler 
  
ring structure $U(G)$ in the case $G=\\Gamma\\times S^1$, with $\\Gamma$ being 
  
comact Lie groups, its connection to the $A(\\Gamma)$-module structure 
  
$A_1^t(G)$ (generated by he twisted orbit types) and some formulae for the 
  
computations of the gradient $G$-degree. The obtained results will be applied 
  
to study the existence of periodic solutions to an elliptic (variational) 
  
asymptotically linear equation with $O(2)$-symmetries $O(2)$.
