Alberto Calderón

Alberto Pedro Calderón was an Argentine-American mathematician, born in Mendoza, Argentina, in 1920. His name is associated with the University of Buenos Aires but first and foremost with the University of Chicago, where he and his mentor Antoni Zygmund developed the theory of singular integral operators, creating what became known as the Chicago School of analysis. His work ranged from singular integral operators to partial differential equations, from interpolation theory to Cauchy integrals on Lipschitz curves, from ergodic theory to inverse problems in electrical prospection, and it has had a powerful impact on signal processing, geophysics and tomography.
