@article{augustová_klapka_2016, title={Atlas as solution of Sincov's inequality}, abstractNote={We find a solution of Sincov's inequality. Further, we prove that in the differentiable case we can interpret such solution as a differentiable manifold in the original sense of Lang. This allows to generalize the notion of atlas and transition map for non-differentiable and discontinuous case.}, author={Augustová and Klapka}, year={2016}, month={Dec} }
