    "abstract": "We use the stability conditions of the Landau parameters for the symmetric\nnuclear matter and pure neutron matter to calculate the critical densities for\nthe Skyrme type effective nucleon-nucleon interactions. We find that the\ncritical density can be maximized by adjusting appropriately the values of the\nenhancement factor $\\kappa$ associated with isovector giant dipole resonance,\nthe quantity $L$ which is directly related to the slope of the symmetry energy\nand the Landau parameter $G_0^\\prime$. However, restricting $\\kappa$, $L$ and\n$G_0^\\prime$ to vary within acceptable limits reduces the maximum value for the\ncritical density $\\tilde\\rho_{cr}$ by $\\sim 25%$. We also show that among the\nvarious quantities characterizing the symmetric nuclear matter,\n$\\tilde\\rho_{cr}$ depends strongly on the isoscalar effective mass $m^*/m$ and\nsurface energy coefficient $E_s$. For realistic values of $m^*/m$ and $E_s$ we\nget $\\tilde\\rho_{cr} = 2\\rho_0$ to $ 3\\rho_0$ ($\\rho_0 = 0.16$fm$^{-3}$).",
