A <connection on a vector bundle> is a complex-linear map $D:\Omega^0(E)\to\Omega^1(E)$ satisfying the <Leibniz rule> $D(fs)=df\otimes s+fDs$. It is compatible with the <Hermitian metric on a holomorphic vector bundle> $h$ when
$$
d\,h(s,t)=h(Ds,t)+h(s,Dt),
$$
and compatible with the holomorphic structure when its type-$(0,1)$ part is the <Dolbeault partial connection>:
$$
\boxed{D^{0,1}=\bar\partial_E.}
$$
