Ernesto Cesàro (12 March 1859 – 12 September 1906) was an Italian mathematician who worked in the field of differential geometry. He wrote a book, Lezioni di geometria intrinseca (Naples, 1896), on this topic, in which he also describes fractal, space-filling curves, partly covered by the larger class of de Rham curves, but are still known today in his honor as Cesàro curves. He is also known for his 'averaging' method for the Cesàro summation of divergent series, also known as the "Cesàro mean".
