Italian mathematician whose most important work was on the theory of functions of real variables. He also conducted studies on surfaces and on some of the work performed by Joseph Liouville and Eugenio Beltrami, solving a difficult problem posed by the latter in one of his publications. Dini is also known for his discovery of the Dini condition, which ensures the convergence of a Fourier series in terms of the convergence of a definite integral.
