there are dierent ways to code the geodesic flows on surfaces with negative curvature. such code spaces give a useful tool to verify the dynamical properties of geodesic flows. here we consider special subspaces of geodesic flows on hecke surface whose arithmetic codings varies on a set with innite alphabet. then we will compare the topological complexity of them by computing their topologica...

• Arithmetic Coding is universal • Arithmetic coding is suitable for small alphabet (binary sources) with highly skewed probabilities. • Huffman cannot allocate fractional bits to symbols: , but the algorithm will assign 1 bit. Huffman needs at least one bit per symbol. If, however, the alphabet is large and probabilities are not skewed, Huffman rate is pretty close to entropy (H). , 01 . 0 , 9...

We study the arithmetic codings of hyperbolic automorphisms of the 2torus, i.e. the continuous mappings acting from a certain symbolic space of sequences with a finite alphabet endowed with an appropriate structure of additive group onto the torus which preserve this structure and turn the two-sided shift into a given automorphism of the torus. This group is uniquely defined by an automorphism,...
