Abstract Let X be a topological space, ( Y , d ) be a metric space, Q ( X , Y ) be the space of quasicontinuous functions from X to Y and τ U C be the topology of uniform convergence on compacta. We study first countability, metrizability and complete metrizability of ( Q ( X , Y ) , τ U C ) . We will apply our results to characterize sequentially compact subsets of ( Q ( X , Y ) , τ U C ) .
