The multiplier representation of the generalized symmetry group of a quasiperiodic flow on
the n-torus defines, for each subgroup of the multiplier group of the flow, a group invariant of …

The generalized symmetry group of a quasiperiodic flow on a n-torus is the group theoretic
normalizer, within the group of diffeomorphisms of the n-torus, of the one parameter abelian …

For quasiperiodic flows of Koch type, we exploit an algebraic rigidity of an equivalence
relation on flows, called projective conjugacy, to algebraically characterize the deviations …

It will be shown that if $\phi $ is a quasiperiodic flow on the $ n $-torus that is algebraic, if
$\psi $ is a flow on the $ n $-torus that is smoothly conjugate to a flow generated by a …

As an absolute invariant of smooth conjugacy, the multiplier group described the types of
space-time symmetries that the flow has, and for a quasiperiodic flow on the $ n $-torus, is …

We classify a quasiperiodic flow as either algebraic or transcendental. For an algebraic
quasiperiodic flow on the n-torus, we prove that an absolute invariant of the smooth …

The nature and the classification of equilibrium-free flows on compact manifolds without
boundary that possess nontrivial generalized symmetries are investigated. Such flows are …
