Sarà ora che ricominci a comprare qualche giornale di carta?
Vladimir I Arnold has made significant contributions to an astounding number of different mathematical disciplines. His many research papers, books, and lectures, plus his enormous erudition and enthusiasm, have had a profound influence on an entire generation of mathematicians. Arnold's Ph.D. thesis contained a solution toHilbert's 13th problem. His work on Hamiltonian dynamics, which includes cocreation of KAM (Kolmogorov- Arnold- Moser) theory and the discovery of "Arnold diffusion", made him world famous at an early age. Arnold's contributions to the theory of singularities complement Thom's catastrophe theory and have transformed this field. Arnold has also made innumerable and fundamental contributions to the theory of differential equations, symplectic geometry, real algebraic geometry, the calculus of variations, hydrodynamics, and magneto- hydrodynamics. He has often discovered links between problems in diverse areas.
