Abstract
We prove that the local eigenvalue statistics in the bulk for complex random matrices with independent entries whose -th absolute moment decays as for some are universal. This includes sparse matrices whose entries are the product of a Bernouilli random variable with mean and an independent complex-valued random variable. By a standard truncation argument, we can also conclude universality for complex random matrices with moments. The main ingredient is a sparse multi-resolvent local law for products involving any finite number of resolvents of the Hermitisation and deterministic matrices whose blocks are multiples of the identity.
