Resumen de Subspaces of Absolutely Star-Lindelöf Spaces
In this paper, we consider two questions on absolute star-Lindelöfness and star-Lindelöfness: (1) Whether every Tychonoff star-Lindelöf space can be embedded into some Tychonoff absolutely star-Lindelöf space as a closed subspace or as a closed Gd-subspace; (2) Characterize the Tychonoff star-Lindelöf spaces which can be embedded as regular closed subspaces into Tychonoff absolutely star-Lindelöf spaces. We proved that the answer to the first question is YES in general. For the second question we give a complete solution.
