In this paper, we have introduced and studied some new notions in topological spaces called λ-US spaces, λ-convergence, sequentially λ-compact sets, sequentially λ-continuous functions, sequentially nearly λ-continuous functions, sequentially λ-compact preserving functions, sequentially sub-λ-continuous functions and λ-Urysohn spaces.
