• In this paper, we consider the following critical quasilinear equation with Hardy potential:

$$$\!\!\!\!\!\left\{ \begin{array}{ll} \!\!\!\!\!-\!\!\sum\limits_{i,j = 1}^N\!\!\!D_j(a_{ij}(u)D_iu)\!+\!\frac{1}{2}\!\!\!\sum\limits_{i,j = 1}^N\!\!\!\!a_{ij}'(u)D_iuD_ju\!+\!a(x)u\! = \!\nu |u|^{q-2}u\!+\!\frac{\mu u}{|x|^2}\!+\!|u|^{2^*-2}u,\hbox{in } \mathbb{R}^N,\\ u(x)\to0\,\,\hbox{as } |x|\,\,\to\infty, \end{array}\right. \;\;\;\;\;(1)$$$

where $a_{ij}(u)\!\in \!C^1\!(\mathbb{R},\mathbb{R})$, $\nu\!>\!0$, $0\!\leq\!\mu\!<\!\alpha\bar{\mu}$, and $\max\!\left\{\!\frac{\alpha\bar{\mu}\gamma}{\alpha\bar{\mu}-\mu}\!+\!2,2^*\!\!-\!\frac{2}{N-2}\sqrt{\!\bar{\mu}\!-\!\frac{\mu}{\alpha}}\right\} \!\!<q<2^*$, $\alpha, \gamma>0$, $\bar{\mu} = \frac{(N-2)^2}{4}$, $2^\ast = \frac{2N}{N-2}$ is the Sobolev critical exponent. And $a(x)$ is a finite, positive potential function satisfying suitable decay assumptions. By using truncation method combining with the regularization approximation approach and compactness arguments, we prove the existence of infinitely many solutions for this equation.
