On three generalizations of the group concept: groupoid, generalized group and almost groupoid
Gheorghe Ivan
The aim of this paper is to describe the definitions and main properties of three generalizations of the group concept, namely: groupoid, generalized group and almost groupoid. Som…

The q-fractional Euler top system with one control on a fractional Leibniz algebroid
Gheorghe Ivan
We determine the fractional almost Poisson realizations for fractional Euler top system with one control. These realizations allow us to introduce a fractional Leibniz algebroid st…

Gheorghe Ivan
The main purpose of this paper is to present a general method for the controllability of the stability of a system of fractional-order differential equations around its equilibrium…
