Abstract
We prove three formulas for computing the topological pressure of -generic conservative diffeomorphism with no dominated splitting and show the continuity of topological pressure with respect to these diffeomorphisms. We prove for these generic diffeomorphisms that there are no equilibrium states with positive measure theoretic entropy. In particular, for hyperbolic potentials, there are no equilibrium states. For generic conservative diffeomorphism on compact surfaces with no dominated splitting and , we show that there exist equilibrium states with zero entropy and there exists a transition point for the one parameter family , such that there is no equilibrium states for and there is an equilibrium state for .

Notes
1 One can find a diffeomorphism such that for each there exists a periodic point p with period m such that has simple eigenvalues such that for each and such that are non-real conjugated complex numbers. Then if f has a dominated splitting on the entire manifold, by continuity of the splitting, we have the dimensions of the finest splitting will be constant which contradicts our construction.
2 For an area-preserving diffeomorphism, if it has a dominated splitting on a compact invariant set, then the splitting is hyperbolic. So is the interior of the set of all non-Anosov diffeomorphisms on M.
