%0 Journal Article %T Extension of continuous functions and weakly developable spaces %A Boualem Alleche %J Mathematics %D 2013 %I arXiv %X The aim of this paper is to investigate weakly developable spaces. For a comparison with semi-metrizable spaces, we introduce and study a class of spaces among those of weakly developable spaces, semimetrizable spaces and first countable spaces having a G_delta-diagonal. Some results are obtained and applications to the problem of extending continuous functions are discussed. %U http://arxiv.org/abs/1309.5484v2
