Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Collating different aspects of Vector-valued Partial Differential Equations and Applications, this volume is based on the 2013 CIME Course with the same name which took place at Cetraro, Italy, under the scientific direction of John Ball and Paolo Marcellini. It contains the following contributions: The pullback equation (Bernard Dacorogna), The stability of the isoperimetric inequality (Nicola Fusco), Mathematical problems in thin elastic sheets: scaling limits, packing, crumpling and singularities (Stefan Muller), and Aspects of PDEs related to fluid flows (Vladimir Sverak). These lectures are addressed to graduate students and researchers in the field.

Virgil Tibbs, the cool, highly-competent black detective of the Pasedena Police Department, returns one day to his bachelor apartment to find that it has been expertly stripped to the bare walls-not a thing remains to show that he has ever lived there. At headquarters he is given a cryptic note from Police Chief McGowan, sending him to a certain address in the better section of Pasedena. When he arrives he finds his possessions carefully installed in a fine new home. But that's not all. The door is opened by a very attractive young woman who informs him that she is Mrs. Virgil Tibbs. He has never seen her before, and he certainly isn't responsible for the two children who greet him as their father. Meanwhile, a brutal holdup is followed by an execution-type hanging of one of the bandits. More violence follows, and Pasedena's ace homicide investigator is tested to the limits by a double assignment calling for every bit of his tact, skill, and discipline. "Tibbs is as much a model of perfection as the late Wimsey... A good detective who actually ratiocinates." -Times Literary Supplement (London
