  De Rham cohomology - Wikipedia, the free encyclopedia
In mathematics, de Rham cohomology (after Georges de Rham) is a tool belonging both to algebraic topology and to differential topology, capable of expressing basic topological information about smooth manifolds in a form particularly adapted to computation and the concrete representation of cohomology classes.

 Georges de Rham - Wikipedia, the free encyclopedia
Georges de Rham (10 September 1903 – 9 October 1990) was a Swiss mathematician, known for his contributions to differential topology.
De Rham himself developed a theory of homological currents, that showed how this fitted with the generalised function concept.
The influence of de Rham’s theorem was particularly great during the development of Hodge theory and sheaf theory.

 PlanetMath: example of de Rham cohomology
The idea of de Rham cohomology is to measure the extent to which closed differential forms are not exact in terms of real vector spaces.
More generally, any contractible manifold has the de Rham cohomology of a point; this is essentially the statement of the Poincaré lemma.

 De_Rham biography
Georges de Rham attended the secondary school Collège d'Aigle from 1914 to 1919 and then at the Gymnase classique de Lausanne from 1919 until 1921.
Having graduated from secondary school with Latin and Greek as his main subjects, de Rham entered the University of Lausanne in 1921 with the intention of studying chemistry, physics and biology.
When I met de Rham in 1949 at the Institute in Princeton he was lecturing on the Hodge theory in the context of his 'currents'.

 RHAM THE UNCIVIL
Rham made gestures to the mass of demons that had encircled them and were closing in with murderous intent on their faces.
Rham made it to his feet and tried to force home an advantage but the demon was no novice warrior, he easily parried the heroes blows, then renewed his own attack.
Rham tried to call after her but he felt a sudden uncontrollable urge to laugh, the urge begun in the bottom of his throat as a tiny titter but by the time it reached his mouth it was a full scale guffaw.

Most of the RHAM smoke bombs were set off during the first 20 minutes of the game as the Sachems sizzled its way to a quick 27-0 lead.
RHAM also blocked a punt, by Ware, of all people, who was pressed into defensive duty Saturday because of an injury to Troy Silva.
RHAM would add to the lead in the second quarter as Tyler Ware (13-for-22, 192 yards) hooked up with Hunter Finnance (4 receptions, 71 yards) on a 29-yard TD pass reception and later found Corey Harrison on a 36-yard pass play to open up a 27-0 lead.

 TuckToday: Spring 2006 - News and Events: Search for the Best
By all accounts, it was de Rham herself who both opened and closed the deal (even though, unlike the competition, she made her presentation by phone, from her home base in San Francisco).
The committee was also intrigued by de Rham's proposal to broaden the search pool, considering candidates from the private sector as well as from academia, especially those with demonstrated success in alternative investments (in which Dartmouth already excelled).
"Amy found me." In the course of their conversation, de Rham sensed that Russ was growing frustrated with the political aspects of his public position and might want to return to what he loved most: pure portfolio management with the flexibility afforded by the private sector.

Lappen and the defense held RHAM (1-6) to a quick three-and-out on its first possession, then took the ball 60 yards on nine plays, using up more than five minutes of the clock to take a 7-0 lead.
Asim Hafeez intercepted a pass on RHAM’s third possession after it was deflected into the air just past the line of scrimmage, giving Rocky Hill the ball on the Terrier 40 late in the first quarter.
RHAM tried once more to climb back in the game down 28-6 with less than eight minutes left, but Lappen’s second pick ended that threat short of the endzone as well.

But then again, the Hebron and RHAM Boards are not known for their ability to work well with other groups or town bodies.
The basis for the letter is a concern that RHAM may have failed to follow their own policy which requires that agencies of all three towns be given an opportunity to express interest in any surplus materials.
The Town of Hebron absorbs 51% of the total bill of the RHAM School system, but when the budgets are brought to election there has been a history of a majority “No” in Hebron, a majority “No” in Andover and a majority “Yes” in Marlborough and a passing budget.

ANDOVER -- When RHAM’s Corey Harrison return of the game’s opening kickoff for a touchdown was followed by two consecutive interceptions and a 50-yard scoring strike, it was obvious that those gathered at Andover Field were in for a show.
This is a RHAM team in it's first year, playing with 30 atheletes (most of whom play both ways with no rest), and they took a highly touted Farmington team to the wire.
RHAM's offence won, RHAM's defense won, Farmington's special team's won - and that was the difference.

Now that the RHAM vote is over, people are probably feeling that they saved tax dollars.
However, the evidence we have uncovered shows us that he is spending those dollars to pay for additional increases in his and his administrative staff's salary and other compensation, as well as other budget overages.
The prior year, he took the $57,000 that people thought was saved in RHAM budget cuts and the money the local Board of Education returned to the town and again used it for his overages.

Why, the series of forms starting with 0-forms (scalar fields), 1-forms (vectors), etc, collectively form what is called the de Rham complex.
