Manuel Kauers (born 20 February 1979 in Lahnstein, West Germany) is a German mathematician and computer scientist.
Together with Doron Zeilberger and Christoph Koutschan, Kauers proved two famous open conjectures in combinatorics using large scale computer algebra calculations.
The first concerned a conjecture formulated by Ira Gessel on the number of certain lattice walks restricted to the quarter plane.
The second conjecture proven by Kauers, Koutschan and Zeilberger was the so-called q-TSPP conjecture, a product formula for the orbit generating function of totally symmetric plane partitions, which was formulated by George Andrews and David Robbins in the early 1980s.
In 2016, with Christoph Koutschan and Doron Zeilberger he received the David P. Robbins prize of the American Mathematical Society.
