Rouché's Theorem
Rouché's theorem, named after Eugène Rouché, states that for any two complex-valued functions and holomorphic inside some region K with closed contour \partial K, if on \partial K, then and have the same number of zeros inside K, where each zero is counted as many times as its multiplicity. This theorem assumes that the contour \partial K is simple, that is, without self-intersections. Rouché's theorem is an easy consequence of a stronger symmetric Rouché's theorem described below. Usage The theorem is usually used to simplify the problem of locating zeros, as follows. Given an analytic function, we write it as the sum of two parts, one of which is simpler and grows faster than (thus dominates) the other part. We can then locate the zeros by looking at only the dominating part. For example, the polynomial z^5 + 3z^3 + 7 has exactly 5 zeros in the disk , z, b > 0). By the quadratic formula it has two zeros at -a \pm \sqrt. Rouché's theorem can be used to obtain mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roche Lobe
In astronomy, the Roche lobe is the region around a star in a binary system within which orbiting material is gravitationally bound to that star. It is an approximately teardrop-shaped region bounded by a critical gravitational equipotential, with the apex of the teardrop pointing towards the other star (the apex is at the Lagrangian point of the system). The Roche lobe is different from the Roche sphere, which approximates the gravitational sphere of influence of one astronomical body in the face of perturbations from a more massive body around which it orbits. It is also different from the Roche limit, which is the distance at which an object held together only by gravity begins to break up due to tidal forces. The Roche lobe, Roche limit, and Roche sphere are named after the French astronomer Édouard Roche. Definition In a binary system with a circular orbit, it is often useful to describe the system in a coordinate system that rotates along with the objects. In this no ...

Roche Limit
In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's gravitational self-attraction. Inside the Roche limit, orbiting material disperses and forms rings, whereas outside the limit, material tends to coalesce. The Roche radius depends on the radius of the first body and on the ratio of the bodies' densities. The term is named after Édouard Roche (, ), the French astronomer who first calculated this theoretical limit in 1848. Explanation The Roche limit typically applies to a satellite's disintegrating due to tidal forces induced by its ''primary'', the body around which it orbits. Parts of the satellite that are closer to the primary are attracted more strongly by gravity from the primary than parts that are farther away; this disparity effectively pulls the ...

The Roches
The Roches were an American vocal trio of sisters Maggie, Terre and Suzzy Roche, from Park Ridge, New Jersey. Career In the late 1960s, eldest sister Maggie (October 26, 1951 – January 21, 2017) and middle sister Terre (pronounced "Terry", born April 10, 1953) attended Park Ridge High School, but dropped out of school to tour as a duo. Maggie wrote most of the songs, with Terre contributing to a few. The sisters got a break when Paul Simon brought them in as backup singers on his 1973 album ''There Goes Rhymin' Simon''. They got his assistance (along with an appearance by the Oak Ridge Boys) on their only album as a duo, '' Seductive Reasoning'' (1975). Reviewing ''Seductive Reasoning'' in '' Christgau's Record Guide: Rock Albums of the Seventies'' (1981), Robert Christgau said, "Female singing duos must function as mutual support groups; last time a women's sensibility this assured, relaxed, and reflective made it to vinyl was Joy of Cooking.

Roche Braziliano
Roche Braziliano (sometimes spelled ''Rock'', ''Roch'', ''Roc'', ''Roque'', ''Brazilliano'', ''Brasiliaan'' or ''Brasiliano'') (c. 1630 – disappeared c. 1671) was a Dutch pirate born in the town of Groningen. His pirate career lasted from 1654 until his disappearance around 1671. He was first made famous in Alexandre Exquemelin's 1678 book ''The Buccaneers of America''; Exquemelin did not know Braziliano's real name, but historians have found he was probably born as Gerrit Gerritszoon and that he and his parents moved to Dutch-controlled Brazil. He is known as "Roche Braziliano", which in English translates to "Rock the Brazilian", due to his long exile in Brazil. Pirate career Roche Braziliano was a notoriously cruel buccaneer who operated out of Port Royal, Jamaica. He was a privateer in Bahia, Brazil, before moving to Port Royal in 1654. He led a mutiny and adopted the life of a buccaneer. On his first adventure he captured a ship of immense value and brought it back safe ...

Roche Baronets
There have been two baronetcies created for persons with the surname Roche, once in the baronetage of Ireland and once in the baronetage of the United Kingdom. One creation is extant as of 2010. The Roche Baronetcy, of Fermoy in the County of Cork, was created on 30 November 1782 for the soldier and politician Sir Boyle Roche. He was childless and the title became extinct on his death in 1807. The Roche Baronetcy, of Carass in Limerick, was created in the baronetage of the United Kingdom on 8 August 1838 for David Roche, Member of Parliament for Limerick. The second baronet was vice-lieutenant and high sheriff of County Limerick. The third baronet was a deputy lieutenant of County Carlow. The fourth baronet was a naval commander.

Roche (crater)
Roche is a large crater on the far side of the Moon from the Earth. The prominent crater Pauli lies across the southern rim of Roche, and the outer rampart of Pauli covers a portion of Roche's interior floor. To the north-northwest of Roche is the crater Eötvös, and just to the west-northwest lies Rosseland. The western rim of Roche has been somewhat distorted and straightened. The rim as a whole is worn and eroded, with multiple tiny craterlets marking the surface. The satellite crater Roche B lies across the northeastern inner wall. The interior floor of Roche is relatively level, but is also marked by several small and tiny craterlets. A grouping of these craters lies near the midpoint. Just to the northwest of this grouping is a bright patch of high-albedo material. Sections of the floor along the north-northwestern side have a lower albedo than elsewhere, usually an indication of basaltic-lava flows similar to what fills the lunar maria. The extent of this patch may act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
