Abstract: Integrals of motion for finite-dimensional systems can be obtained using the brute force method, symmetries of configuration space, relations with nonlinear evolution equations, using Lax matrices, methods of bi-Hamiltonian geometry, etc. In this talk, we discuss a new combination of Nether's symmetry method with the brute force method that allows us to get three new families of integrable systems in n-dimensional Euclidean space. A few of such systems are related to the Hermitian symmetric space theory and to the multi component nonlinear Schrodinger equations hierarchy.
