Abstract:In this paper, we study multiplicity of positive solutions for a class of Kirchhoff type of equations with the nonlinearity containing both singularity and critical exponents. We obtain two positive solutions via the variational and perturbation methods.
“…This equation extends the classical D'Alembert wave equation for free vibrations of elastic strings, which takes into account the changes in length of the string produced by transverse vibrations; while purely longitudinal motions of a viscoelastic bar of uniform cross section and its generalizations can be found in [2][3][4][5][6][7][8]. A distinguishing feature of equation ( the equation is no longer a pointwise identity.…”
In this paper, we deal with the Kirchhoff-type equationwhere λ > 0, V and Q are radial functions, which can be vanishing or coercive at infinity. With assumptions on f just in a neighborhood of the origin, existence and multiplicity of nontrivial radial solutions are obtained via variational methods.In particular, if f is sublinear and odd near the origin, we obtain infinitely many solutions of (P) λ for any λ > 0.Mathematics Subject Classification. 35J50 · 35J60 · 35J65.

“…on a smooth bounded domain Ω ⊂ R 3 and f : Ω×R → R a continuous function, has been extensively studied (see [1,3,10,11,[15][16][17]19,18,20,23,24,30]). Particularly, in [24] Sun and Tang have considered the following problem…”

“…In particular, when λ = 1, p = 5, problem (1.4) has at least two solutions for μ > 0 small enough, such as [2,6,12,25,[27][28][29]. However, the singular Kirchhoff type problems have few been considered, except for [15] and [17]. Liu and Sun in [17] have investigated problem (1.2) with f (x, u) = g(x)u −γ + λh(x) u p |x| s , and g, h ∈ C(Ω), 0 ≤ s < 1, 3 < p < 5 − 2s.…”

“…They proved that the non-degenerate case of problem (1.2) has at least two positive solutions for λ > 0 small enough by the Nehari manifold. More recently, Lei, Liao and Tang in [15] have considered the non-degenerate case of problem (1.2) with f (x, u) = u 5 + μu −γ , that is, problem (1.2) with singularity and critical exponents. By the variational methods, we obtained that problem (1.2) has at least two positive solutions for μ > 0 small enough.…”
In this work, we study a class of Kirchhoff type problems with singularity and nonlinearity, and obtain the uniqueness and existence of positive solutions of those problems by the variational methods. Furthermore, we obtain the multiplicity of positive solutions of those problems by the Nehari method.
In this paper, we consider the quasilinear elliptic equation with singularity and critical exponentsis a critical Sobolev-Hardy exponent. We deal with the existence of multiple solutions for the above problem by means of variational and perturbation methods.
