Gyula Vályi (5 January 1855, Marosvásárhely/Târgu Mureş – 13 October 1913, Kolozsvár/Cluj) was a Hungarian mathematician and theoretical physicist, a member of the Hungarian Academy of Sciences, known for his work on mathematical analysis, geometry, and number theory.
Vályi was born in Marosvásárhely, the town of the famous mathematicians Farkas Bolyai and János Bolyai. He attended the Reformed College in Marosvásárhely . After graduating from school, he went to Kolozsvár, the capital of Transylvania, where he attended the Franz Joseph University.
After qualifying as a teacher of mathematics and physics Vályi was awarded a scholarship to allow him to study for two years at the University of Berlin, where the remarkable mathematics team of Kummer, Borchardt, Weierstrass and Kronecker were lecturing.
His doctoral dissertation was on the theory of partial differential equations of the second order. His thesis was published at Kolozsvár in 1880 and can be found to this day in the library of the Faculty of Mathematics of Babes-Bolyai University. In 1881 he became a dozent at the University of Kolozsvár. Vályi was appointed professor of theoretical physics in 1884, and in 1885 he also became professor of mathematics lecturing on analysis, geometry and number theory. One of his favorite courses was concerned with János Bolyai's "Appendix". He was elected a corresponding member of the Hungarian Academy of Sciences in 1891.
