Abstract

We prove the existence of primitive curves and positivity of intersections of JJ-complex curves for Lipschitz-continuous almost complex structures. These results are deduced from the Comparison Theorem for JJ-holomorphic maps in Lipschitz structures, previously known for JJ of class C1,LipC^{1, Lip}. We also give the optimal regularity of curves in Lipschitz structures. It occurs to be C1,LnLipC^{1,LnLip}, i.e. the first derivatives of a JJ-complex curve for Lipschitz JJ are Log-Lipschitz-continuous. A simple example that nothing better can be achieved is given. Further we prove the Genus Formula for JJ-complex curves and determine their principal Puisieux exponents (all this for Lipschitz-continuous JJ-s).
