| Abstract: | In this paper some properties concerning the notion of quasi H{\mathcal{H}} -closedness in topological spaces are obtained. Locally quasi H{\mathcal{H}} -closed spaces are studied. Properties of these types of spaces are investigated, when the subsets involved are α-open, semi-open, clopen, or preopen. |
