Christian Gustav Adolph Mayer

Christian Gustav Adolph Mayer (15 February 1839 – 11 April 1908) was a German mathematician.

His research on the integration of partial differential equations and a search to determine maxima and minima using variational methods brought him close to the investigations that Sophus Lie was carrying out around the same time.

Several letters were exchanged between Mayer and mathematician Felix Klein from 1871 to 1907.

Those letters provide insights into the scientific and personal relations among Felix Klein, Mayer and Lie over the period.

Mayer's students included Friedrich Engel, Felix Hausdorff and Gerhard Kowalewski.
