With a population of 650,900 living in an area of , it is the most densely populated region in the world. - East Asia is the eastern subregion of the Asian continent, which can be defined in either geographical or ethno-cultural terms. Geographically and geopolitically, it includes China, Hong Kong, and Macao; Mongolia and Taiwan; North and South Korea; and Japan; it covers about , or about 28% of the Asian continent, about twice the area of Europe. - The Pearl River Delta (PRD), also known as Zhujiang Delta or Zhusanjiao, is the low-lying area surrounding the Pearl River estuary, where the Pearl River flows into the South China Sea. It is one of the most densely urbanised regions in the world and is an economic hub of China. This region is often considered an emerging megacity. The PRD is a megalopolis, with future development into a single mega metropolitan area, yet itself is at the southern end of a larger megalopolis running along the southern coast of China, which include metropolises such as Chaoshan, Zhangzhou-Xiamen, Quanzhou-Putian, and Fuzhou. The nine largest cities of PRD had a combined population of 57.15 million at the end of 2013, comprising 53.69% of the provincial population. According to the World Bank Group, the PRD has become the largest urban area in the world in both size and population. - Guangdong (Simplified ) is a province on the South China Sea coast of the People's Republic of China. Formerly romanised as Canton or Kwangtung, Guangdong surpassed Henan and Sichuan to become the most populous province in China in January 2005, registering 79.1 million permanent residents and 31 million migrants who lived in the province for at least six months of the year; the total population was 104,303,132 in the 2010 census, accounting for 7.79percent of Mainland China's population.

Q: Information: - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. - Nigel James Hitchin FRS (born 2 August 1946) is the Savilian Professor of Geometry at Oxford University and a British mathematician working in the fields of differential geometry, algebraic geometry, and mathematical physics. - Geoffrey Horrocks ( 1932/33 Leicester - 12 September 2012 ) was a British mathematician working on vector bundles , who introduced the Horrocks construction used in the ADHM construction , and the Horrocks -- Mumford bundle and monads . He was a professor at Newcastle University until his retirement in 1998 . - An instanton (or pseudoparticle) is a notion appearing in theoretical and mathematical physics. An instanton is a classical solution to equations of motion with a , non-zero action, either in quantum mechanics or in quantum field theory. More precisely, it is a solution to the equations of motion of the classical field theory on a Euclidean spacetime. - Sir Michael Francis Atiyah (born 22 April 1929) is an English mathematician specialising in geometry. - The River Soar is a major tributary of the River Trent in the English East Midlands and is the principal river of Leicestershire. The source of the river is midway between Hinckley and Lutterworth. The river then flows north through Leicester, where it is joined by the Grand Union Canal. Continuing on through the Leicestershire Soar Valley, it passes Loughborough and Kegworth until it reaches the Trent at the county boundary. In the 18th century, the Soar was made navigable, initially between Loughborough and the Trent, and then through to Leicester. It was not until the early 19th century that it was linked by the Grand Union Canal to the wider network to the south and to London. - Vladimir Gershonovich Drinfeld (born February 14, 1954), surname also romanized as Drinfel'd, is a Ukrainian mathematician currently working at the University of Chicago. - Leicester is a city and unitary authority area in the East Midlands of England, and the county town of Leicestershire. The city lies on the River Soar and at the edge of the National Forest. - In mathematical physics, the ADHM construction or monad construction is the construction of all instantons using methods of linear algebra by Michael Atiyah, Vladimir Drinfeld, Nigel Hitchin, Yuri I. Manin in their paper "Construction of Instantons". - Leicestershire (or ; abbreviation Leics.) is a landlocked county in the English Midlands. It takes its name from the City of Leicester, traditionally its administrative centre, although the City of Leicester unitary authority is today administered separately from the rest of Leicestershire. The county borders Nottinghamshire to the north, Lincolnshire to the north-east, Rutland to the east, Northamptonshire to the south-east, Warwickshire to the south-west, Staffordshire to the west, and Derbyshire to the north-west. The border with most of Warwickshire is Watling Street (the A5). Given the information, choose the subject and object entities that have the relation of 'field of work'.
