Andrea Malchiodi, Vittorio Coti Zelati · Advanced Nonlinear Studies · 2012
Antonio Ambrosetti is an outstanding mathematicians who greatly contributed to the advancement of modern Nonlinear Analysis by introducing new fundamental tools and ideas and applying them to study significant applications.We only recall here the paper in collaboration with his maestro Giovanni Prodi, On the inversion of some differentiable mapping with singularities between Banach spaces, Ann.Mat.Pura Appl., 93 (1972) and the paper in collaboration with Paul Rabinowitz, Dual variational methods in critical point theory and applications, J. Functional Analysis, 14 (1973).Both of them had a great impact on the mathematical community and have helped shape modern Nonlinear Analysis.Antonio is a great teacher and has had positive influence on many mathematicians in Italy and abroad.We both had such an opportunity, while being graduate students at SISSA, and we have experienced personally on one hand his deep mathematical knowledge and his enthusiasm for mathematics and on the other side his patience, his willingness to listen (also to our mistakes) and to collaborate on an equal footing (even with young, inexperienced Ph.D. student like we were).
