Poisson Lie groups, bi Hamiltonian systems and integrable deformations

A characterization in terms of range functions for translations given by the left regular representation of nilpotent Lie groups whose irreducible represen- tations are

Motivated by the previous results of Fabricio Maci` a and Gabriel Rivi` ere on the dynamics of the Schr¨ odinger equation associated with small perturbations of completely

We have stud- ied the relation between higher-order Lagrangian systems with constraints (nonholonomics and vakonomics) and higher-order Hamiltonian systems, the reduction by

Carleson’s celebrated theorem of 1965 [14] asserts the pointwise convergence of the partial Fourier sums of square integrable functions.. We give a proof of this fact, in particular

The theory is modelled on the p-local homotopy theory of classifying spaces of compact Lie groups and p-compact groups, and generalises the earlier concept of p-local finite
