Summability methods are transformations that map sequences (or functions) to sequences (or functions). A prime requirement for a "good" summability method is that it preserves convergence. Unless it is the identity transformation, it will do more: it will transform some divergent sequences to convergent sequences. An important type of theorem is called a Tauberian theorem. Here, we know that a sequence is summable. The sequence satisfies a further property that implies convergence. Borel's methods are fundamental to a whole class of sequences to function methods. The transformation gives a function that is usually analytic in a large part of the complex plane, leading to a method for analytic continuation. These methods, dated from the beginning of the 20th century, have recently found applications in some problems in theoretical physics.

A riveting account of one of the most remarkable episodes in American history.
In his critically acclaimed history "Freedom Summer," award- winning author Bruce Watson presents powerful testimony about a crucial episode in the American civil rights movement. During the sweltering summer of 1964, more than seven hundred American college students descended upon segregated, reactionary Mississippi to register black voters and educate black children. On the night of their arrival, the worst fears of a race-torn nation were realized when three young men disappeared, thought to have been murdered by the Ku Klux Klan. Taking readers into the heart of these remarkable months, Freedom Summer shines new light on a critical moment of nascent change in America.

In these, his memoirs, we see Harry's adolescent revolt against his all-powerful father and his flight to Canada after knocking him down in a row. Then there is the account of his adventures in the Lincolnshire Regiment before the outbreak of the First World War, his time in the trenches with the rats and the corpses and only his belief in the Almighty and in his Destiny to keep him going. He tells how he lost a fortune during the Depression, and then made another that he was to fritter away in luxury cruises in the last years of his life. The Second World War gives him a new 'raison d'etre' - first in the Home Guard and then in the 'Little Ships.'

He paints a vivid picture of a forgotten way of life, a life of ease, of loss, of heartbreak, and of adventure; though, strangely enough, he never speaks of his personal feelings - it wasn't the done thing.

He was fiercely proud and patriotic and adored all royalty and aristocracy, delighting in any occasion that permitted him to approach them. But his greatest pride was that of being, first and foremost, 'a Lincolnshire man.'

This is the story of one of America's most divisive trials and executions. Ferdinando Sacco and Bartolomeo Vanzetti were two Italian-born anarchists tried and executed for robbery in 1927 despite widespread doubt about their guilt and whether they received a fair trial. This book tells the story and includes the official FBI files.

This collection of snappy, humorous, earthy stories all have a sting in the tail. They portray aspects of life in France unsuspected by most casual visitors. Food and sex are rarely talked of with such delicate earthiness. Medicine, herbal remedies, crime, social niceties, witchcraft and religion are the reflecting mirrors that illuminate Fanny, Louis, Francine and Justin: the larger-than-life characters who invite you to share their France with you.

On January 12, 1912, an army of textile workers stormed out of the mills in Lawrence, Massachusetts, commencing what has since become known as the "Bread and Roses" strike. Based on newspaper accounts, magazine reportage, and oral histories, Watson reconstructs a Dickensian drama involving thousands of parading strikers from fifty-one nations, unforgettable acts of cruelty, and even a protracted murder trial that tested the boundaries of free speech. A rousing look at a seminal and overlooked chapter of the past, Bread and Roses is indispensable reading.
