摘要

In this paper, we study the global existence of weak solutions for parabolic Kirchhoff-type problems of the following form: \(\begin{aligned} {\left\{ \begin{array}{ll} u_t+ M(\Vert u\Vert _{W_0}^p)(-\Delta )_p^s u+\pi _{p\theta }(u)=\pi _{p\theta }(u)\log (\vert u\vert ) & \text{ in } \Omega , \quad t>0,\\ u(x, 0)=u_0(x) & \text{ in } \Omega \\ u=0 & \text{ in } (\mathbb {R}^n \backslash \Omega ),\quad t>0, \end{array}\right. } \end{aligned}\) u t + M ( u W 0 p ) ( - Δ ) p s u + π p θ ( u ) = π p θ ( u ) log ( | u | ) in Ω , t > 0 , u ( x , 0 ) = u 0 ( x ) in Ω u = 0 in ( R n \ Ω ) , t > 0 , where \(\Omega \subset \mathbb {R}^n\) Ω R n , \(\pi _{p\theta }(x)=\vert x\vert ^{p\theta -2}x\) π p θ ( x ) = | x | p θ - 2 x , \(1\le \theta <\frac{p_s^*}{p}\) 1 θ < p s p , \(2< p<\frac{n}{s}\) 2 < p < n s , \(0<s<1\) 0 < s < 1 , \(M: \mathbb {R}^+\rightarrow \mathbb {R}^+\) M : R + R + is a continuous function defined by \(M(r)=r^{\theta -1}\) M ( r ) = r θ - 1 and \((-\Delta )_p^s\) ( - Δ ) p s is the fractional p-Laplacian operator. Based on the potential well method combined with the theory of Young measures and the Galerkin method, we obtain the existence of global solution.
