Abstract

Let $(M,g)$ be a smooth compact Riemannian $n$-manifold, $n \ge 3$. Let also $p \ge 1$ be an integer, and $M_p^s({\mathbb R})$ be the vector space of symmetrical $p\times p$ real matrices. For $A: M \to M_p^s({\mathbb R})$ smooth, $A = (A_{ij})$, we consider vector-valued equations, or systems, like $$\Delta_g^p{\mathcal U} + A(x){\mathcal U} = \frac{1}{2^\star}D_{{\mathcal U}}\vert{\mathcal U}\vert^{2^\star}, $$ where ${\mathcal U}: M \to {\mathbb R}^p$ is a $p$-map, $\Delta_g^p$ is the Laplace-Beltrami operator acting on $p$-maps, and $2^\star$ is critical from the Sobolev viewpoint. We investigate various questions for this equation, like the existence of minimizing solutions, the existence of high energy solutions, blow-up theory, and compactness. We provide the complete $H_1^2$-theory for blow-up, sharp pointwise estimates, and prove compactness when the equations are not trivially coupled and of geometric type.
