It has been proved that for n not less than 2, there exists an annulus-busting curve in δHm. In the present paper, we prove that for n not less than 2, there exists an essential simple closed curve C in OHm which intersects each essential planar surface in Hn non-emptily. Furthermore, we show that for n not less than 3, a pants-busting curve must also be an annulus-busting curve.展开更多

These remittances to developing countries are expected to reach $516 billion in 2016, an increase from the $404 billion recorded in 2013, according to the International Monetary Fund （IMF）. Global remittances to Africa tripled from $19.5 billion in 2004 to $63.8 billion in 2014, according to the World Bank.展开更多
