contents I prove "Lefschetz principle"-type theorems for semistable and curve semistable Higgs sheaves on smooth projective varieties defined over an algebraically closed field of characteristic $0$. These theorems are applied to reduce a conjecture, about curve semistable Higgs bundles, from the previous general setting to the complex case. Since this conjecture is equivalent to vanishing of Chern classes of H-nflat Higgs bundles, I consider these last ones over elliptic surfaces. I reduce one more time the conjecture to nilpotent, H-nflat Higgs bundles, and I prove it on elliptic surfaces.
