AB - We report on results we recently obtained in Hebey and Thizy [11, 12] for critical stationary Kirchhoff systems in closed manifolds. Let $(M^n,g)$ be a closed $n$-manifold, $n \ge 3$. The critical Kirchhoff systems we consider are written as\begin{equation*} \Bigl (a + b\sum _{j=1}^p\int _M\vert \nabla u_j\vert ^2dv_g\Bigr )\Delta _gu_i + \sum _{j=1}^pA_{ij}u_j = \left|U\right|^{2^\star -2}u_i \end{equation*}for all $i = 1,\dots ,p$, where $\Delta _g$ is the Laplace-Beltrami operator, $A$ is a $C^1$-map from $M$ into the space $M^p_s(\mathbb{R})$ of symmetric $p\times p$ matrices with real entries, the $A_{ij}$’s are the components of $A$, $U = (u_1,\dots ,u_p)$, $\vert U\vert : M \rightarrow \mathbb{R}$ is the Euclidean norm of $U$, $2^\star = \frac{2n}{n-2}$ is the critical Sobolev exponent, and we require that $u_i \ge 0$ in $M$ for all $i = 1,\dots ,p$. We discuss the two following issues in this text: the question of the existence of nontrivial solutions to our systems, together with the dual question of getting nonexistence results in parallel to our existence results, and the question of the stability of our systems which measures how much the equations are robust with respect to variations of their natural parameters $a$, $b$, and $A$.
