On the basis of exactly solvable models with the tricritical and criticalendpoints I discuss the physical mechanism of endpoints formation which issimilar to the usual liquids. It is demonstrated that the necessary conditionfor the transformation of the 1-st order deconfinement phase transition intothe 2-nd order phase transition at the (tri)critical endpoint is the vanishingof surface tension coefficient of large/heavy QGP bags. Using the novel modelof the confinement phenomenon I argue that the physical reason for thecross-over appearance at low baryonic densities is the negative value of QGPbag surface tension coefficient. This implies the existence of highlynon-spherical or, probably, even fractal surfaces of large and heavy bags atand above the cross-over, which, perhaps, can be observed via somecorrelations. The model with the tricritical endpoint predicts that at thedeconfinement transition line the volume (mass) distribution of large (heavy)QGP bags acquires the power law form at the endpoint only, while in the modelwith the critical endpoint such a power law exists inside the mixed phase. Therole of finite width of QGP bags is also discussed.
