He married eight times: Ruth Boyd ( 1940 – 1947 ), dancer Marion Bell ( 1947 – 1949 ), Nancy Olson ( 1950 – 1957 ), lawyer Micheline Muselli Pozzo di Borgo ( 1957 – 1965 ), editor Karen Gunderson ( 1966 – 1974 ), Sandra Payne ( 1974 – 1976 ), Nina Bushkin ( 1977 – 1981 ) and Liz Robertson ( 1981 – 1986 death ).

When Pat Buchanan and Pat Robertson addressed Christian themes at the Republican National Convention – with Bush criticizing Democrats for omitting God from their platform – many moderates were alienated.

The cosmological principle implies that the metric should be homogeneous and isotropic on large scales, which uniquely singles out the Friedmann – Lemaître – Robertson – Walker metric ( FLRW metric ).

The uncertainty principle is ultimately a theorem about such commutators, by virtue of the Robertson – Schrödinger relation.

* 1995 – Robertson Davies, Canadian novelist ( b. 1913 )

To dispel remaining doubt about the Appel – Haken proof, a simpler proof using the same ideas and still relying on computers was published in 1997 by Robertson, Sanders, Seymour, and Thomas.

* 1982 – Neil Robertson, Australian snooker player

The best-known exact solutions, and also those most interesting from a physics point of view, are the Schwarzschild solution, the Reissner – Nordström solution and the Kerr metric, each corresponding to a certain type of black hole in an otherwise empty universe, and the Friedmann – Lemaître – Robertson – Walker and de Sitter universes, each describing an expanding cosmos.

In 1996, Neil Robertson, Daniel P. Sanders, Paul Seymour, and Robin Thomas created a quadratic time algorithm, improving on a quartic algorithm based on Appel and Haken ’ s proof (; ).

A simpler proof considering only 633 configurations was given twenty years later by Robertson, Seymour, Sanders and Thomas.

The snark theorem, a result conjectured by W. T. Tutte and announced in 2001 by Robertson, Sanders, Seymour, and Thomas, states that every snark has the Petersen graph as a minor.

In the current decade the Matroid Minors Project of Geelen, Gerards, Whittle, and others, which attempts to duplicate for matroids that are representable over a finite field the success of the Robertson – Seymour Graph Minors Project ( see Robertson – Seymour theorem ), has produced substantial advances in the structure theory of matroids.

In graph theory, the Robertson – Seymour theorem ( also called the graph minor theorem ) states that the undirected graphs, partially ordered by the graph minor relationship, form a well-quasi-ordering.

The Robertson – Seymour theorem states that finite undirected graphs and graph minors form a well-quasi-ordering.

According to the Robertson – Seymour theorem, there exists a finite set H of minimal elements in S. These minimal elements form a forbidden graph characterization of F: the graphs in F are exactly the graphs that do not have any graph in H as a minor.

The Robertson – Seymour theorem states that the relation " being a minor of " is a well-quasi-ordering on the isomorphism classes of graphs, and implies that many other families of graphs have forbidden minor characterizations similar to that for the planar graphs.

A deep result by Neil Robertson and Paul Seymour states that this partial order is actually a well-quasi-ordering: if an infinite list G < sub > 1 </ sub >, G < sub > 2 </ sub >,... of finite graphs is given, then there always exist two indices i < j such that G < sub > i </ sub > is a minor of G < sub > j </ sub >.

In the course of their proof, Seymour and Robertson also prove the graph structure theorem in which they determine, for any fixed graph H, the rough structure of any graph which does not have H as a minor.

call it “ one of the deepest unsolved problems in graph theory .” Another result relating the four-color theorem to graph minors is the snark theorem announced by Robertson, Sanders, Seymour, and Thomas, a strengthening of the four-color theorem conjectured by W. T. Tutte and stating that any bridgeless 3-regular graph that requires four colors in an edge coloring must have the Petersen graph as a minor.

The topological minor relation is not a well-quasi-ordering on the set of finite graphs and hence the result of Robertson and Seymour does not apply to topological minors.

The immersion minor relation is a well-quasi-ordering on the set of finite graphs and hence the result of Robertson and Seymour applies to immersion minors.

The conjecture remained unresolved for 40 years, until it was established as the celebrated strong perfect graph theorem in 2002 by Chudnovsky, Robertson, Seymour, Thomas 2002.

# REDIRECT Robertson – Seymour theorem

For example, the Robertson – Seymour theorem guarantees that there is a finite list of forbidden minors that characterizes ( for example ) the set of graphs that can be embedded on a torus ; moreover, Robertson and Seymour showed that there is an O ( n < sup > 3 </ sup >) algorithm for determining whether a graph has a given graph as a minor.

This was finally proven as the strong perfect graph theorem of Chudnovsky, Robertson, Seymour, and Thomas ( 2006 ).

* Finite graphs ordered by a notion of embedding called " graph minor " is a well-quasi-order ( Robertson – Seymour theorem ).

Therefore, by the Robertson – Seymour theorem, the linklessly embeddable graphs have a forbidden graph characterization as the graphs that do not contain any of a finite set of minors.

As observed, linklessly embeddable graphs are closed under graph minors, from which it follows by the Robertson – Seymour theorem that a forbidden graph characterization exists.

* Throughout Robertson Davies's The Manticore a comparison is repeatedly made between the protagonist's problematic relations with his father and those of between the Biblical Absalom and King David.

In 2007, Geoffrey Robertson QC alleged that Phillip's remains are no longer in St Nicholas Church, Bathampton and have been lost: "... Captain Arthur Phillip is not where the ledger stone says he is: it may be that he is buried somewhere outside, it may simply be that he is simply lost.

" It is known that Clan MacCallum and Clan Malcolm are descended from the original followers of Columba, It is also said that Clan Robertson are heirs of Columba.

The attribution is held to be anachronistic however by J J O ' Connor and E F Robertson who name Theon of Alexandria as a more likely author.

Robertson ( 2007 ) reasoned that if evolution is accelerated in conditions of propagative difficulty, then we would expect to encounter variations of religious memes, established in general populations, addressed to scientific communities.

* Minerva is featured in the logo of The Mac. Robertson Girls ' High School, Australia.

In his forenote to the novel, King wrote, " Don Robertson was and is one of the three writers who influenced me as a young man who was trying to ' become ' a novelist ( the other two being Richard Matheson and John D.

Robertson is credited as writer or co-writer for the majority of The Band's songs, but sang lead vocals on only three of their studio recordings (" To Kingdom Come ", " Knockin ' Lost John " and " Out Of The Blue ").

The campus is well-known to Islanders of all ages, from children who take part in Panther day camps or come to varsity games, to adults who use the Robertson Library or take classes through Seniors College.

Clark teaches in the Robertson School of Government and the School of Global Leadership & Entrepreneurship and is a member of the Regent's Board of Trustees.

* December 25 – Fort Nashborough, later to become Nashville, Tennessee, is founded by James Robertson.

The act is named for Nevada Senator Key Pittman and Virginia Congressman Absalom Willis Robertson.

Also it is known that Robertson did not climb the Inaccessible Peak of Sgùrr Dearg.

If Robertson is discounted, the first Munroist is Ronald Burn, who completed in 1923.

Marion Gordon " Pat " Robertson ( born March 22, 1930 ) is a media mogul, television evangelist, ex-Baptist minister and businessman who politically aligns himself with the Christian Right in the United States.

The son of U. S. Senator A. Willis Robertson, Robertson is a Southern Baptist and was active as an ordained minister with that denomination for many years, but holds to a charismatic theology not traditionally common among Southern Baptists.

Robertson is also an advocate of Christian dominionism — the idea that Christians have a right to rule.

Robertson is the founder and chairman of The Christian Broadcasting Network ( CBN ) Inc., and founder of International Family Entertainment Inc., Regent University, Operation Blessing International Relief and Development Corporation, American Center for Law and Justice, The Flying Hospital, Inc. and several other organizations and broadcast entities.
