Jorge Luis Borges, one of the indisputably great writers of the twentieth century, was born in Buenos Aires in 1899. Never having been awarded the Nobel Prize, which his readers worldwide believed he deserved, this story writer, poet, essayist, and man of letters died at age eighty-six.

This anthology of interviews with him features more than a dozen conversations that cover all phases of his life and work.

Conducted between 1964 and 1984, the interviews reveal Borges to be a remarkably candid, humorous man, by turns skeptical and enthusiastic, and always a singularly incisive and...

This new volume shows how it is possible to further develop and essentially extend the theory of operators in infinite-dimensional vector spaces, which plays an important role in mathematics, physics, information theory, and control theory. The book describes new mathematical structures, such as hypernorms, hyperseminorms, hypermetrics, semitopological vector spaces, hypernormed vector spaces, and hyperseminormed vector spaces. It develops mathematical tools for the further development of functional analysis and broadening of its applications.

Exploration of semitopological...

"Hypernumbers and Extrafunctions" presents a rigorous mathematical approach to operate with infinite values. First, concepts of real and complex numbers are expanded to include a new universe of numbers called hypernumbers which includes infinite quantities. This brief extends classical calculus based on real functions by introducing extrafunctions, which generalize not only the concept of a conventional function but also the concept of a distribution. Extrafucntions have been also efficiently used for a rigorous mathematical definition of the Feynman path integral, as well as for...

Performing Life is a richly illustrated biography of the internationally renowned violinist Ruth Posselt (1911--2007), tracing her career from her debut as a child prodigy at New York's Carnegie Hall in 1923 to her last appearances in the late seventies. This first-ever biography details Posselt's struggles with the widespread gender bias against female violinists as well as the lesser-known prejudice of American audiences and managers against American-born virtuosos. But Performing Life focuses on Posselt's achievements, especially her pioneering work in premiering and popularizing...
