I will describe several works dealing with the construction of different solutions on lattices.
I will first investigate the problem of pulsating trvaelling waves known as travelling breathers.
I will secondly deal with qusi-periodic motions on the lattice via a KAM theorem. I will construct finite dimensional and infinite dimensional invariant tori.
