Recursive behavior in a diatomic FPUT lattice
Guo Deng, Andrea Pezzi, Genghong Lin +1
We study the diatomic FPUT lattice with cubic anharmonic potential, and analyze the recurrent behaviour of its solutions. We find that two distinct types of recurrence occur. One t…

Three-wave resonant interactions in the diatomic chain with cubic anharmonic potential: theory and simulations
A. Pezzi, G. Deng, Y. Lvov +2
We consider a diatomic chain characterized by a cubic anharmonic potential. After diagonalizing the harmonic case, we study in the new canonical variables, the nonlinear interactio…

2nd order PDEs: geometric and functional considerations
Andrea Pezzi
INTRODUCTION This papers deals with partial differential equations of second order, linear, with constant and not constant coefficients, in two variables, which admit real characte…
