Query: On the Hausdorff Dimension of Piecewise Hyperbolic Attractors   We study non-invertible piecewise hyperbolic maps in the plane. The Hausdorff
dimension of the attractor is calculated in terms of the Lyapunov exponents,
provided that the map satisfies a transversality condition. Explicit examples
of maps for which this condition holds are given.
