Given an integer, and aAnosov flowon some compact connected 3-manifold preserving a smooth volume, we show that the measure of maximal entropy is the volume measure if and only ifis-conjugate to an algebraic flow, forarbitrarily small. Moreover, in the case of dispersing billiards, we show that if the measure of maximal entropy is the volume measure, then the Birkhoff Normal Form of regular periodic orbits with a homoclinic intersection is linear.
