He has visited many mathematical institutions all over the world (among them universities at Aarhus, Pisa, Paris and ETH in Zurich).

In 1978 Paul Rabinowitz became a fellow of the John Simon Guggenheim Memorial Foundation.

However also the linking and saddle point theorems, results concerning the existence of periodic solutions to hamiltonian systems, variational methods in the theory of critical points of strongly indefinite functional under the absence of compactness conditions of the Palais–Smale type and other achievements of Paul Rabinowitz have found their place in the history of mathematics.

He is the recipient of numerous honors and awards, including the George David Birkhoff Prize in 1998.

[4] In 2014 Paul Rabinowitz was awarded with the Juliusz Schauder Medal,[5] the prize established by the Juliusz Schauder Center for Nonlinear Studies at the Nicolaus Copernicus University in Toruń, Poland, in recognition of his important contribution in the field of topological methods in nonlinear analysis.
