Richard Stanley – författare

In April of 1996 an array of mathematicians converged on Cambridge, Massachusetts, for the Rotafest and Umbral Calculus Workshop, two con­ ferences celebrating Gian-Carlo Rota's 64th birthday. It seemed appropriate when feting one of the world's great combinatorialists to have the anniversary be a power of 2 rather than the more mundane 65. The over seventy-five par­ ticipants included Rota's doctoral students, coauthors, and other colleagues from more than a dozen countries. As a further testament to the breadth and depth of his influence, the lectures ranged over a wide variety of topics from invariant theory to algebraic topology. This volume is a collection of articles written in Rota's honor. Some of them were presented at the Rotafest and Umbral Workshop while others were written especially for this Festschrift. We will say a little about each paper and point out how they are connected with the mathematical contributions of Rota himself.

Richard Stanley's two-volume basic introduction to enumerative combinatorics has become the standard guide to the topic for students and experts alike. This thoroughly revised second edition of volume two covers the composition of generating functions, in particular the exponential formula and the Lagrange inversion formula, labelled and unlabelled trees, algebraic, D-finite, and noncommutative generating functions, and symmetric functions. The chapter on symmetric functions provides the only available treatment of this subject suitable for an introductory graduate course and focusing on combinatorics, especially the Robinson-Schensted-Knuth algorithm. An appendix by Sergey Fomin covers some deeper aspects of symmetric functions, including jeu de taquin and the Littlewood-Richardson rule. The exercises in the book play a vital role in developing the material, and this second edition features over 400 exercises, including 159 new exercises on symmetric functions, all with solutions or references to solutions.

Ronald Reagans legacy as president is nearly unparalleled in American history due to his domestic and foreign policy leadership. Reagans contrarian insistence on advocating limited government and supply-side economics drew much bipartisan criticism, causing the Great Communicator to take his argument that lowering taxes would encourage economic growth directly to the people. The result? Congress granted $750 billion in tax cuts in 1981. The Reagan Revolution had begun. By mid-1983, the nations economy was booming. On President Reagans first day in office, the Iran Hostage Crisis finally came to an end. Fifty-two American embassy personnel held hostage by a defiant Iran during the last four hundred-plus days of the Carter administration were freeda definite win for all Americans. But Reagan soon was widely criticized for insulting Russias leaders by calling the Soviet Union the evil empire. Later, Reagan was criticized at home and abroad for challenging Soviet premier Gorbachev to tear down the Berlin Wall. Reagans most criticized proposal of all, however, was his insistence on developing his Strategic Defense Initiative (SDI)space weapons to defend America from incoming Soviet nuclear missiles. Domestic critics dismissed his proposal as a Star Wars fantasy (but the Soviets feared SDI). By December 1991, it was clear that Reagans Star Wars fantasy helped cause the bankruptcy and total collapse of the Soviet Union, bringing a peaceful end to the decades-long Cold War.

An investigation into the Holy Grail and the Cathar legacy• Traces the journey of Otto Rahn, the occultist and one-time SS member who sought the Holy Grail and traveled widely throughout Europe as a researcher until his mysterious death in 1939• Explores the modern legacy of the officially heretical Christian sect known as the Cathars• Follows the author’s own investigations into the location of the Grail and Rahn’s legacy, taking readers on a journey through occult EuropeMeticulously following controversial 20th-century occultist, historian, and partially Jewish SS member Otto Rahn’s investigations into the Holy Grail and Catharism, author and filmmaker Richard Stanley enters into the occult world of Europe. On his quest, the author encounters esoteric traditions that have survived since the Crusades and the Inquisition, ultimately finding a new spiritual path in his own life. At Rahn’s family home in the Black Forest of Germany, Stanley unearths a cache of maps, photographs, and unpublished manuscripts. His journey in pursuit of Rahn’s legacy then takes him to Montségur, in southern France, a mystical stronghold and one-time home of the Cathars, the esoteric and Gnostic Christian sect that was decimated in the medieval Albigensian Crusade. There he sees the extraordinary summer solstice light phenomenon that reveals the mystical past of the fortress and encounters witnesses who insist Rahn is still alive.Methodically visiting every site on Otto Rahn’s esoteric path, from France to Iceland, the author untangles legend from truth as he looks at the connections between the Cathars, the Rosicrucians, Julius Evola, neo-Cathar and Freemason Déodat Roché, and the mystical bleeding stones known as Lapsit exillis. He also examines the prophecy of the return of Esclarmonde de Foix, the White Lady, medieval priestess of the Cathars who appeared to Rahn during his search for the Grail.
