supports: Gloucester is a city and district in southwest England, the county city of Gloucestershire. Gloucester lies close to the Welsh border, on the River Severn, between the Cotswolds to the east and the Forest of Dean to the southwest. Rollo Davidson ( b. Bristol , 8 October 1944 , d. Piz Bernina , 29 July 1970 ) was a probabilist , alpinist , and Fellow - elect of Churchill College , Cambridge , who died aged 25 on Piz Bernina . He is known for his work on semigroups , stochastic geometry , and stochastic analysis , and for the Rollo Davidson Prize , given in his name to young probabilists . Bristol is a city, unitary authority area and county in South West England with an estimated population of 449,300 in 2016. It is England's sixth and the United Kingdom's eighth most populous city, and the most populous city in Southern England after London. The city borders the Unitary Authority areas of North Somerset and South Gloucestershire, with the historic cities of Bath and Gloucester to the south-east and north-east, respectively. Churchill College is a constituent college of the University of Cambridge, England. It has a primary focus on science, engineering and technology, but still retains a strong interest in the arts and humanities. Cambridge is a university city and the county town of Cambridgeshire, England, on the River Cam about north of London. At the United Kingdom Census 2011, its population was 123,867, including 24,488 students. In mathematics, stochastic geometry is the study of random spatial patterns. At the heart of the subject lies the study of random point patterns. This leads to the theory of spatial point processes, hence notions of Palm conditioning, which extend to the more abstract setting of random measures. In probability theory, a random measure is a measure-valued random element. Let X be a complete separable metric space and formula_1 the -algebra of its Borel sets. A Borel measure  on X is boundedly finite if (A) <  for every bounded Borel set A. Let formula_2 be the space of all boundedly finite measures on formula_1. Let be a probability space, then a random measure maps from this probability space to the measurable space .A measure generally might be decomposed as: The Alps are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across eight Alpine countries: Austria, France, Germany, Italy, Liechtenstein, Monaco, Slovenia, and Switzerland. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the FrenchItalian border, and at is the highest mountain in the Alps. The Alpine region area contains about a hundred peaks higher than 4000 metres (just over 13,000 feet). Eastern Alps is the name given to the eastern half of the Alps, usually defined as the area east of a line from Lake Constance and the Alpine Rhine valley up to the Splügen Pass at the Alpine divide and down the Liro River to Lake Como in the south. The peaks and mountain passes are lower compared to the Western Alps, while the range itself is broader and less arched. Gloucestershire (; abbreviated Glos.) is a county in South West England. The county comprises part of the Cotswold Hills, part of the flat fertile valley of the River Severn, and the entire Forest of Dean. Somerset is a county in South West England which borders Gloucestershire and Bristol to the north, Wiltshire to the east, Dorset to the south-east and Devon to the south-west. It is bounded to the north and west by the Severn Estuary and the Bristol Channel, its coastline facing southeastern Wales. Its traditional border with Gloucestershire is the River Avon. Somerset's county town is Taunton. Piz Bernina is the highest mountain in the Eastern Alps, the highest point of the Bernina Range, and the highest peak in the Rhaetian Alps. It is also the most easterly mountain higher than in the Alps, the highest point of the Swiss canton of Graubünden, and the fifth-most prominent peak in the Alps. Piz Bernina is located south of Pontresina and near the major Alpine resort of St. Moritz, in the Engadin valley. A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges. The Rollo Davidson Prize is a prize awarded annually to early-career probabilists by the Rollo Davidson trustees. It is named after English mathematician Rollo Davidson (19441970). 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. London is the capital and most populous city of England and the United Kingdom, as well as the most populous city proper in the European Union. Standing on the River Thames in the south east of the island of Great Britain, London has been a major settlement for two millennia. It was founded by the Romans, who named it "Londinium". London's ancient core, the City of London, largely retains its medieval boundaries. Since at least the 19th century, "London" has also referred to the metropolis around this core, historically split between Middlesex, Essex, Surrey, Kent, and Hertfordshire, which today largely makes up Greater London, governed by the Mayor of London and the London Assembly. The Engadin or Engadine (, , ; lit.: "Valley of the Inn people") is a long high Alpine valley region in the eastern Swiss Alps located in the canton of Graubünden in most southeastern Switzerland with about 25,000 inhabitants. It follows the route of the Inn from its headwaters at Maloja Pass in the southwest running roughly northeast until the Inn flows into Austria, one hundred kilometers downstream. The En/Inn subsequently flows at Passau into the Donau, as the only Swiss river. The Engadine is protected by high mountain ranges on all sides and is famous for its sunny climate, beautiful landscapes and outdoor activities. The Rhaetian Alps are a mountain range of the Eastern Alps. The SOIUSA classification system divides them into the Western and Eastern Rhaetian Alps, while the Alpine Club classification of the Eastern Alps places most of the Rhaetion subranges within the Western Limestone Alps.
  They are located along the ItalianSwiss and AustrianSwiss borders, in the canton of Graubünden in eastern Switzerland; in the state of Tyrol in Austria; and in the Italian regions of Trentino-Alto Adige and Lombardy.
