The paper Entropy of continuous flows on compact 2-manifolds was published in Topology and shows that a continuous one-dimensional flow on a 2-dimensional manifold has zero topological entropy.
Ang papel Entropy ng patuloy na daloy sa mga compact 2-manifolds ay nai-publish sa Topology at nagpapakita na ang isang patuloy na isa-dimensional dumaloy sa isang 2-dimensional karamihan ay zero topological entropy.
