Fractional dynamicsFractional dynamics is a field of study in physics and mechanics, studying the behavior of physical systems that are described by usingintegrations of noninteger (fractional) orders,differentiation of noninteger (fractional) orders.
Equations with derivatives and integrals of fractional orders are used to describe objects that are characterized by powerlaw nonlocality, powerlaw longterm memory, fractal properties.

History of fractional calculusFractional calculus is a theory of integrals and derivatives of any arbitrary real (or complex) order.
It has a long history from 30 September 1695, when the derivatives of order 1/2 has been described by Leibniz in a letter to L'Hospital
The fractional differentiation and fractional integration go back to many great mathematicians such as Leibniz, Liouville, Riemann, Abel, Riesz, Weyl.

Semigroup property ?* /42QFTHEP 2010
QFTHEP 2010

The dynamical maps with noninteger cannot form a semigroup. This property means that we have a nonMarkovian evolution of quantum systems.
The dynamical maps describe quantum dynamics of open systems with memory.The memory effect means that the present state evolution depends on all past states.

ConclusionsEquations of the solutions describe nonMarkovian evolution of quantum coordinate and momentum of open quantum systems.
This fractional nonMarkovian quantum dynamics cannot be described by a semigroup. It can be described only as a quantum dynamical groupoid.
The longterm memory of fractional open quantum oscillator leads to dissipation with powerlaw decay.
