%0 Journal Article %T Multifractal analysis for Birkhoff averages on Lalley-Gatzouras repellers %A Henry WJ Reeve %J Mathematics %D 2010 %I arXiv %X We consider the multifractal analysis for Birkhoff averages of continuous potentials on a class of non-conformal repellers corresponding to the self-affine limit sets studied by Lalley and Gatzouras. A conditional variational principle is given for the Hausdorff dimension of the set of points for which the Birkhoff averages converge to a given value. This extends a result of Barral and Mensi to certain non-conformal maps with a measure dependent Lyapunov exponent. %U http://arxiv.org/abs/1008.0301v2
