 Theory of Linear Operations (North-Holland Mathematical Library)The theory of operators, created by V. Volterra, has as its object the study of functions defined on infinite-dimensional spaces. This theory has penetrated several highly important areas of mathematics in an essential way: suffice it to recall that the theory of integral equations and the calculus of variations are included as special cases within... |  |  Mobius and his Band: Mathematics and Astronomy in Nineteenth-Century GermanyAugust Mobius was one of the 19th century's most influential mathematicians and astronomers. Written by six distinguished contributors, this book explores the work of Mobius and his brilliant German contemporaries. The work emphasizes those achievements which in many ways can be seen to reflect the exciting advances taking place at the time... |  |  |
