Siavoshi %J Mathematics %D 2015 %I arXiv %X The $\lambda$-perfect maps, a generalization of perfect maps (continuous closed maps with compact fibers) are presented. Using $P_\lambda$-spaces and the concept of $\lambda$-compactness some results regarding $\lambda$-perfect maps will be investigated. %U http://arxiv.org/abs/1502.00170v1
