The Collected Papers of Raoul Bott are contained in five volumes, with each volume covering a different subject and each representing approximately a decade of Bott's work. The volumes are:
Volume 1: Topology and Lie Groups (1950's)
Volume 2: Differential Operators (1960's)
Volume 3: Foliations (1970's)
Volume 4: Mathematics Related to Physics (1980's)
Volume 5: Completive Articles and Additional Biographic Material (1990's)
There is no doubt that the volume will be of immense importance for all interested in modern topology and/or Bott's legacy.
-- Zentralblatt f?r Mathematik (Review of Vol. 1)
Each reader will certainly profit from Bott's elegant style and engagement with the central problems of the subject and time.
-- Mathematical Reviews (review of Vol. 1)
The volume (along with the three other volumes) is highly recommended to any mathematical library, institutional as well as individual...
-- Mathematical Reviews (Review of Vol. 2)
The volume will be indispensible in every topological library.
