For this purpose we will introduce a new covariant derivative for dynamical systems and derive desired equation by help of the derivative.

Generators of Dynamical Systems on Hilbert Modules
Of course, δ∗ ( x∗ ) := δ( x)∗ defines a ternary derivation of E ∗ with domain dom(δ∗ ) := dom(δ)∗ , and by Theorem 3.5 there is a unique ∗ –derivation dδ∗ of K(E ) defined on the domain dom(dδ∗ ) = span(cid:0)dom(δ) dom(δ)∗ (cid:1), defines a ∗ –derivation turning δ∗ into a dδ∗ –derivation.
Generators of Dynamical Systems on Hilbert Modules
If δ is a ternary derivation, the derivation dδ plays a distinguished role as it is related more directly to questions of closability than any other derivation d that turns δ into a d –derivation.
Generators of Dynamical Systems on Hilbert Modules
In other words, every derivation d that turns a closable ternary derivation δ of a full Hilbert B –module into a d –derivation admits a unique minimal closed extension d ′ ⊃ dδ , and δ is also a d ′ –derivation. 3.12 Theorem.
Generators of Dynamical Systems on Hilbert Modules
In general, a d –derivation (even bounded) of a full Hilbert B –module for some derivation d of B need not be a ternary derivation, not even if d is a bounded ∗ –derivation.
