“…Consider It is easy to see that the linearization of the first equation of (3.10) is given by In the following, we study the eigenvalues of the operator Q. Motivated by [18] and [28], we shall see that Q can be expressed in terms of Fourier expansions of spherical harmonics. All these vector spherical harmonics form a normalized orthogonal basis of (L 2 (S 2 )) 3 (see Appendix A of [18] and [23]).…”

“…is linearly asymptotically stable for small μ/γ, that is, there exists a threshold value (μ/γ) * such that if μ/γ < (μ/γ) * , then the trivial solution of the linearization at (σ * , v * , p * , Ω * ) of the original problem is asymptotically stable, while if μ/γ > (μ/γ) * , then the trivial solution is unstable. Later on, Wu and Cui improved this linear asymptotic stability to asymptotic stability for the quasi-stationary model in [28], and finally extended this asymptotic stability result to the fully non-stationary model for small c 1 in [29]. The literature [32] is also mentioned for the study of analyticity of the free boundary in time and space variables for the quasi-stationary model.…”

“…Introduction. During the past few decades, an increasing number of mathematical models describing tumor growth with a free boundary have been studied and developed in many papers; see [1,2,3,4,5,7,8,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51] and the references therein. These models usually contain one or more reaction-diffusion equations describing the concentration of substrates such as nutrients and inhibitors, and one or several first-order nonlinear partial differential equations describing the evolution and mov...…”

“…When Darcy's law is replaced by Stokes equations, Friedman and Hu found a critical value N * (R S , γ) in [29] such that the radially symmetric stationary solution is linearly stable if µ/γ < N * (R S , γ) and linearly unstable if µ/γ > N * (R S , γ). Later on, it was proved that there exists a threshold value γ * > 0 for the adhesiveness coefficient γ such that if γ > γ * then the radially symmetric stationary solution is asymptotically stable with respect to nonradial perturbations, while γ < γ * this stationary solution is unstable in [46] and [47]. In the presence of inhibitors, the stability of the radially symmetric stationary solution was studied in [48].…”
