Pick interpolation and Hilbert function spaces

The book first rigorously develops the theory of reproducing kernel Hilbert spaces. The authors then discuss the Pick problem of finding the function of smallest $H^\infty$ norm that has specified values at a finite number of points in the disk. Their viewpoint is to consider $H^\infty$ as the multiplier algebra of the Hardy space and to use Hilbert space techniques to solve the problem. This approach generalizes to a wide collection of spaces. The authors then consider the interpolation problem in the space of bounded analytic functions on the bidisk and give a complete description of the solution. They then consider very general interpolation problems. The book includes developments of all the theory that is needed, including operator model theory, the Arveson extension theorem, and the hereditary functional calculus.

In this rich compilation, Emeka Nwosu takes the reader to a journey of the issues that have helped to shape discourses on various aspects of the Nigerian state and society. The articles, originally published in his weekly column in the premier Nigerian daily newspaper, ThisDay, not only show his perspectives on these issues when they were written but also reveal how discussions on some of those issues have evolved over time and how they have mutated today.

Journalists, especially those who maintain regular columns, are often said to write 'history in a hurry'. For experienced writers like the author whose writings are research-based, it does not mean that what they write about is factually wrong but simply that their writings are infused with the passions and emotions that attended those issues as they unfolded.

This collection is therefore not only informed commentaries on some of the issues that have shaped the contour of the Nigerian state and society over the years but a good trip on the passions and emotions that attended those discourses. The articles, 66 of them, are written with remarkable candour and gusto and therefore a delight to read. They form a very important contribution to the corpus of works on Nigerian politics and society.

"e;MARTIN RATTLER"e; was one of, Robert Michael Ballantyne's early books. Born at Edinburgh in 1825,[1] he was sent to Rupert's Land as a trading-clerk in the Hudson Bay Fur Company's service when he left school, a boy of sixteen. There, to relieve his home-sickness, he first practised his pen in long letters home to his mother. Soon after his return to Scotland in 1848 he published a first book on Hudson's Bay. Then he passed some years in a Scottish publisher's office; and in 1855 a chance suggestion from another publisher led to his writing his first book for boys-"e;Snowflakes and Sunbeams, or The Young Fur Traders."e; That story showed he had found his vocation, and he poured forth its successors to the tune in all of some fourscore volumes. "e;Martin Rattler"e; appeared in 1858. In his "e;Personal Reminiscences"e; Ballantyne wrote: "e;How many thousands of lads have an intense liking for the idea of a sailor's life!"e; and he pointed out there the other side of the romantic picture: the long watches "e;in dirty unromantic weather,"e; and the hard work of holystoning the decks, scraping down the masts and cleaning out the coal-hole. But though his books show something of this reverse side too, there is no doubt they have helped to set many boys dreaming o
