The investigation of strongly interacting systems ranges from matter inside atomic nuclei to matter under extreme conditions in astrophysics. These systems require the introduction of nuclear forces and a systematic many-body approach to solve the strong interaction particles. Understanding the behavior of infinite nuclear matter provides a path to predict the properties of neutron stars and gives insights to astrophysical phenomena. Three-nucleon forces have to be considered when studying nuclear systems, because their impact is necessary to reproduce properties of nuclei and to correctly obtain the neutron drip line. Moreover, they are needed to predict the empirical saturation properties of infinite nuclear matter. The self-consistent Green’s Function approach paves the way for an improved
*Ab initio* analysis of nuclear matter, thereby providing the basis for the equation of state of neutron stars and supernova explosions.

The Brueckner-Hartree-Fock (BHF) approach was used in the study of hot nuclear systems. The BHF approximation takes into account particle-particle correlations by solving the Bethe-Goldstone equation. On the other hand, a minimal consistent treatment of correlations in nuclear systems requires the addition not only of particle-particle intermediate states, but also of the hole-hole ones. One important feature of the self-consistent Green function (SCGF) approximation is that particles and holes are treated on equal footing. The effect of the hole-hole term is small at low densities and becomes larger at higher densities. In a recent work [

1) The free energy which was calculated according to Equation (13) is correct because it contains two variables m* and T. But, the author used it with wrong method. m* was taken as constant values where it is in fact a function of density. So the figures (1 - 10) are drawn with wrong method. Also, the effect of temperature is not being real with this method [

2) It is noted that the author has added a wrong correction to the three-body force. The author claims in the abstract, text and conclusion that he used 3-body corrections in order to get an agreement with the experimental data besides his BHF calculation. In Equations 8 - 10, he gave the name of a potential v_{i} on the LHS where such terms are in fact the contribution to the energy per particle (E/A)_{i} from Skyrme potentials v_{i} which are not written in the paper. The potentials used to get such results are, respectively, a zero range two-body Skyrme potential which is density independent. The second term is a zero range two-body Skyrme interaction which is density dependent. For the last one, this is equivalent to the inclusion of a three-body force. Therefore, the first term should be excluded from the calculation as this contradicts his assumptions of using 3-body forces. Hence, any further calculation in the paper using such potentials where one of them is density independent is wrong and should be repeated in a correct manner. It is noted that Mansour’s three-body potential given in reference [
