Summary: We consider elliptic systems of divergence form in $$\mathbb R^n$$ under the limited smoothness assumptions on the coefficients. We construct $$L^p$$ resolvents with evaluation of their operator norms, and derive the Gaussian bounds for heat kernels and estimates for resolvent kernels. These results extend those for single operators.
