 ">Cascades of singular rational surfaces of Picard number one</a>\nby Dong
 Seon Hwang (Ajou) as part of Online Nottingham algebraic geometry seminar\
 n\n\nAbstract\nI will introduce the notion of cascades of singular rationa
 l surfaces of Picard number one\, which consists of a sequence of special 
 birational morphisms\, and then discuss some applications in the toric cas
 e\, Fano case\, and (log) general type case. The latter application is clo
 sely related to algebraic Montgomery-Yang problem\, conjectured by Kollár
