Born Mar. 12, 1859, in Naples; died Sept. 12, 1906, in Torre Annunziata, near Naples. Italian mathematician.
Cesaro was a professor at the University of Naples. In 1880 he developed methods of finding the sum of divergent series. Cesaro made important contributions to intrinsic geometry, in which curves and surfaces are defined in terms of quantities that do not change under transformations of coordinates.
