Equivalence of Different Hereditary Structures in Ordinary Differential Equations

Cristina Marcelli, Anna Salvadori
1998 Journal of Differential Equations  
We prove that different formulations of hereditary settings for ordinary differential systems, which appeared not comparable, are actually equivalent.  ...  Academic Press This formulation was extended to different directions; we recall, for example, the following hereditary structures, where g(t, x) t [11]; x$(t)= f \ t, | E t h(s, x(s)) ds + (b) article  ...  (P 2 ) As the authors remark in [3] , this abstract formulation includes and unifies many classes of hereditary differential equations which are applied in various fields (see, e.g., [11, 17, 12, 10]  ...

The Lie Algebra Structure of Nonlinear Evolution Equations Admitting Infinite Dimensional Abelian Symmetry Groups

B. Fuchssteiner
1981 Progress of theoretical physics  
861 Hereditary operators in Lie algebras are investigated.  ...  In order to construct new hereditary operators out of given ones we study the permanence properties of these operators; this study of permanence properties leads in a natural way to a notion of compatibility  ...  Here the linear dependence in A is rather special. And, of course, there is a more general structure having linear deformations as tangential structure.  ...

Fractional order state equations for the control of viscoelasticallydamped structures

1991 Journal of Guidance Control and Dynamics  
The hereditary nature of the structural equations suppresses the existence of homogeneous solutions found in the state equations.  ...  This is necessary for heavily damped structures. In lightly damped structures the hereditary effects are much smaller, and the pseudoforces may be ignored.  ...
