Farkas gave conditions for the solvability of Schröder's functional equation in 1884. His results in hydrodynamics and thermodynamics were discussed in the second volume of the Woldemar Voigt's ‘Mathematische Physik’, published in 1896. His physics papers were mathematically rigorous and at the same level as other contemporary papers on physics.
