Following an exposition of the applications, the book develops underlying theory. Many topics are presented in a novel way, with an emphasis on explicit and computations. Further examples, as well as new theoretical developments, appear in the exercises at the end of each chapter differential equations,lie groups Minh, 971015 Trung tâm Học liệu Trường Đại học Cần Thơ
