High and low temperature behavior of a quantum group fermion gas
  We consider the simplest $SU_{q}(2)$ invariant fermionic hamiltonian and calculate the low and high temperature behavior for the two distinct cases $q>1$ and $q<1$. For low temperatures we find that entropy values for the Fermi case are an upper bound for those corresponding to $q\neq 1$. At high temperatures we find that the sign of the second virial coefficient depends on $q$, and vanishes at $q=1.96$.   An important consequence of this fact is that the parameter $q$ connects the fermionic and bosonic regions, showing therefore that $SU_{q}(2)$ fermions exhibit fractional statistics in three spatial dimensions.
