Rigid centres on the center manifold of tridimensional differential systems
(2021-01-01)
Motivated by the definition of rigid centres for planar differential systems, we introduce the study of rigid centres on the center manifolds of differential systems on ℝ3. On the plane, these centres have been extensively ...
Rigid and semi rigid polyurethane resins: a structural investigation using DMA, SAXS and Le Bail method
(Elsevier BVAmsterdam, 2014-10)
Two different types of polyurethane (PU) resins were synthesized with pre-polymer/polyol (-NCO/-OH) mass proportions of 1:1 (Rigid PU) and 1:1.5 (Semi rigid PU). Based on the results from Dynamic Mechanical Analysis (DMA), ...

The Nash–Moser theorem of Hamilton and rigidity of finite dimensional nilpotent Lie algebras
(Elsevier Science, 2017-09)
We apply the Nash–Moser theorem for exact sequences of R. Hamilton to the context of deformations of Lie algebras and we discuss some aspects of the scope of this theorem in connection with the polynomial ideal associated ...

Spinning rigid bodies driven by orbital forcing: the role of dry friction
(2022-01-01)
A “circular orbital forcing” makes a chosen point on a rigid body follow a circular motion while the body spins freely around that point. We investigate this problem for the planar motion of a body subject to dry friction. ...
