Web2 iun. 2013 · It enables us to deal with non-analytic Hamiltonians, and in this first part we will focus on Gevrey Hamiltonians and derive normal forms with an exponentially small remainder. This extends a result which was known for analytic Hamiltonians, and only in the periodic case for Gevrey Hamiltonians. ... A Diophantine Duality Applied to the KAM and ... Web19 mai 2024 · We prove a new invariant torus theorem, for $α$-Gevrey smooth Hamiltonian systems , under an arithmetic assumption which we call the $α$-Bruno-R{ü}ssmann condition , and which reduces to the classical Bruno-R{ü}ssmann condition in the analytic category. Our proof is direct in the sense that, for analytic Hamiltonians, we avoid the use …
