# Alberto P. Calderon

Wolf Prize Laureate in Mathematics 1989

The Mathematics Prize Committee has unanimously selected the following two candidates to equally share the 1989 Wolf Prize in Mathematics: John W. Milnor and Alberto P. Calderon.

**Alberto P. Calderon**

**University of Chicago**

**Chicago, Illinois, USA**

“for his groundbreaking work on singular integral operators and their application to and important problems in partial differential equations.”

The work of Professor Alberto P. Calderon has had a lasting impact on the shape of contemporary Fourier analysis and on its connections with real variables, complex analysis, and partial differential equations. In particular, his contributions to the theory of singular integral operators (SIO) have been decisive, both through the introduction of the sharpest technical tools into that theory and through its imaginative application to important problems in partial differential equations.

Together with his teacher, Antoni Zygmund, Calderon proved the famous theorem on the LP boundedness .
