%0 Journal Article %T Sobriety and Localic Compactness in Categories of -Bitopological Spaces %A Kamal El-Saady %A M. Y. Bakier %J International Journal of Mathematics and Mathematical Sciences %D 2007 %I Hindawi Publishing Corporation %R 10.1155/2007/54689 %X The notions of L-sobriety and L-spatiality are introduced for the category L-BiTop of L-bitopological spaces. Such notions are used to extend the known adjunction between the category L-Top of L-topological spaces and the category Loc of locals to one between the category L-BiTop and BiLoc. Also, the concepts of localic regularity and localic compactness are introduced in the mentioned category. %U http://www.hindawi.com/journals/ijmms/2007/054689/abs/
