  "abstract": "In this paper, we present a bootstrap procedure for general elliptic systems with $n(\\geq 3)$ components. Combining with the $L^p$-$L^q$-estimates, it yields the optimal $L^\\infty$-regularity conditions for the three well-known types of weak solutions: $H_0^1$-solutions, $L^1$-solutions and $L^1_\\delta$-solutions. Thanks to the linear theory in $L^p_\\delta(\\Omega)$, it also yields the optimal conditions for a priori estimates for $L^1_\\delta$-solutions. Based on the a priori estimates, we improve known existence theorems for some classes of elliptic systems.",
